Why is concrete batching plant replacing manual concrete production

 We know that most of the construction sites are very busy now. Every day, tens of thousands of tons of materials are transported on the construction site. At the same time, the construction of various departments on the construction site is very busy. However, those with past construction site experience will find that now on the construction site, it is rarely seen that workers are mixing cement by themselves. In the past, we always saw a cement pit, where workers worked hard to mix, but now this situation is almost gone. All concrete production work is replaced by concrete batching plants. Why do building contractors would rather spend extra money on commercial concrete rather than having workers to mix concrete at a much lower cost?

　　First of all, different construction sites have different requirements for concrete mixing. A single building might require more than a dozen different cement types. It is difficult for workers to manually produce concrete of such precise standards, so in order to ensure the quality of concrete , This work must be handed over to a more standardized and professional concrete mixing plants.

　　Secondly, there is not much open space for stacking materials on the construction site. Most of the places are stacked with reinforced concrete and some other materials. Therefore, in order to allow more free space on the construction site for scheduling, the concrete is directly transported from the mixing station. It will squeeze out the space that is not much.

　　Finally, concrete production itself is also a behavior prone to pollution, and a lot of dust and other pollutants are still produced during the mixing process. This may cause workers to contract lung diseases or some skin diseases, and bring air and noise pollution to the surrounding area.

　　Concrete batching plant manufacturers have solved the above problems perfectly. The popularity of concrete batching plants not only provides accurate proportioning of concrete for the modern construction industry, but also reduces pollution. Even the mixing plant itself is usually equipped with decontamination equipment to reduce pollution to nearby areas. In addition, the concrete mixing plant helps the people in charge of the construction site save labor costs and speed up the progress of the project. Generally speaking, it is more cost-effective than the traditional method of producing concrete on the spot.

Aggregate loading methods for mobile batching plants

 Two loading methods are usually available for aggregate conveying of mobile and stationary concrete batching plants: bucket loading and belt conveying. The advantages of hopper feeding include low cost, small footprint, and simple structure. The disadvantage is that the feeding speed is not as fast as the belt speed. The advantages of belt feeding are that the feeding is much faster, and the conveying distance is large, the efficiency is high, and the failure rate is low. The disadvantage is that the cost is high.

Generally speaking, purchasers of commercial concrete mixing plants are definitely advised to configure the belt feeding method. The suitable mixing station models for belt feeding methods mainly include HZS60 concrete batching plant, HZS90 concrete batching plant, HZS120 concrete batching plant, HZS180 concrete batching plant and HZS240 concrete batching plant. Because of the high efficiency of belt feeding and transportation, it can quickly complete large-scale operations and improve production efficiency by over 20%; and the belt feeding production cycle is short, and the discharge capacity is large, which is suitable for commercial concrete mixing plants. Smaller models of batching plants are usually equipped with bucket loaders.

With that said, a mobile batching plant should have a bucket loader as the aggregate loading device. This, however, is not the case at all. No matter it’s a small plant like a mobile batching plant 40t, or a large mobile plant of 75m3 per hour, its standard configuration for aggregate loading system is a belt conveyor. Why?

 

Judged by capacity range, all mobile batching plants should be matched with bucket loaders, for their largest capacity does not exceed 75m3. Nevertheless, they have belt conveyors regardless of the capacity. This is to cater for the requirement of high mobility of the plants. The belt conveyor frame of Haomei mobile concrete batching plant in ethiopia or other countries is a truss structure that connects the main chassis and the aggregate batching frame, and is equipped with a belt rack; the main frame, the belt rack, and the batching frame are combined to form the main structure of the entire mobile mixing station. This design not only helps to reduce installation time of the plant, but also enhances site transfer speed greatly.

Why Is Your Automatic Concrete Mixer Machine Low Efficient

 An automatic concrete mixer machine should provide cast-in-place concrete to the construction site in the form of centralized premixing and long-distance transportation. This is a high-tech building material product that combines modern concrete with modern construction technology. Modern buildings, highways, railways, bridges, airports, etc. are inseparable from concrete pouring, so concrete mixing plants have become popular products in these industries. As we all know, the use of a concrete mixer in the open air is exposed to wind, sun, and rain throughout the year. After a period of use, it will easily become inefficient. The reasons are as follows.

????1. The raw material preparation time is longer than the mixing and discharge time. Since the preparation of various raw materials needs to be completed after the preparation is completed, in this case, there is a lot of idle time in the whole process, which can only wait for the preparation work, which greatly reduces the workload and the efficiency of each workflow. The corresponding workload cannot be completed within the time unit.

????2. The raw material preparation time is less than or equal to the sum of the two. The calculation of work efficiency in the concrete production process is relatively large, that is to say, if the total production time is too long, it will destroy the entire concrete production balance and work efficiency will be low.

????3. Failure to perform maintenance in a timely and regular manner. After use, the concrete mixer should clean the inside and outside of the mixing barrel in time, and use a clean adhesive to remove it properly. The mixing blade should be tightened once a week to prevent the blade from falling and causing accidents. Regularly check the shaft end seal cavity and the inlet and outlet of the distributor. Check whether the sealing line is smooth, full of grease, and whether each lubrication point and gearbox has enough grease. Observe whether the grease in the storage cylinders of the electric lubrication pumps at all levels is used up. The lubricating oil should be filled up in time after use, and it is not allowed to run without oil.

????In short, the low production efficiency of automatic concrete mixer machines may be related to the production process and maintenance habits. As long as you pay attention to the above aspects, the production efficiency of the mixer can be guaranteed.

ajy50 mobile concrete batching plant price

 An ajy50 mobile concrete batching plant is a yhzs50 mobile batching plant, the capacity of which is 50m3 per hour. The price varies from supplier to supplier.

The ajy50 mobile batching plant consists of a JS1000 concrete mixer with a power of 37kw and mixing period 72s, a PLD1600 batching machine with a rated input volume of 1600L and a standard aggregate bin capacity 3*5m3, and a belt conveyor. The overall weight of the plant is around 26 tons and the installation power 92kw. The plant is of modular structure, which suits movement well. Cement, water and liquid admixture ingredients are all measured by electronic scales with high accuracy. The water supply system uses water pumps to speed up the water flow rate and spray evenly. The control system adopts imported components with printing function and air-conditioning. The required site is small, which can save one-half to two-thirds of the land occupation area compared with the usual stationary concrete batching plant with inclined belt conveying and loading.

 

The ajy50 mobile concrete batching plant price varies from supplier to supplier. The cheapest is only around 60,000 dollars. Needless to say, the price of a plant always matches its quality and service life. What’s more, the configuration of 50m3 mobile batching plants from different suppliers may differ slightly, too. Therefore, you need to contact a supplier directly and tell them your practical needs about concrete production before getting a specific price.

Diesel and electric mini trailer concrete pumps, which one i

 A mini trailer concrete pump falls on two types divided by power kinds: diesel and electric. Diesel powered and electric powered concrete pumps have their own advantages. Electricity drives are more economical and environmentally friendly. However, they need to be connected to the grid and require sufficient power. This is not suitable in remote rural areas and the wild. Diesel power does not need to be connected. Connected to the grid, but fuel consumption is more expensive than electricity, and it is polluting.

　　As the name suggests, electric mini concrete pumps use electricity to drive the equipment pouring and construction. As long as the construction place can meet the power supply of the equipment, it means that the equipment can be constructed normally as long as it can be connected to three-phase electricity. The motor power used by the small concrete pump is calculated according to KW. Because the construction efficiency of delivering 5 cubic meters of material per hour must be completed, it is important that the construction is not interrupted. In places with sufficient electricity, wires are sold everywhere, and the price is not expensive, which is more economical than small diesel-powered pumps.

　　In addition, an electric mini concrete pump is very environmentally friendly during construction, and will not cause some pollution near the construction as the diesel-powered equipment is constructed, and it is not easy to clean. As long as the electric small transfer pump does not block the pipe, the normal power supply voltage will not cause pollution to the construction, eliminating some links of cleaning and cleaning. There are three types of motor power: 5.5kw, 11kw and 5kw according to different models. The greater the flow and head requirements, the greater the motor power is required. A variety of different motor powers are available, making construction more convenient.

　　To sum up, electric mini concrete pumps are better than diesel ones in both efficiency and energy cost. If the external power is sufficient and convenient, you can choose an electric trailer pump, which has lower energy consumption costs and lower prices. Otherwise, you have to use diesel pumps. Of course, the working location of the trailer pump is not static. If an electric trailer pump goes to the wilderness without electricity, what should you do? In response to this problem, many cement pump machine manufacturers have equipped their trailer pumps with diesel-electric dual-power systems. However, this is generally for larger trailer pumps, for small trailer pumps are rarely confronted with this problem.

How to choose mobile batching plant mixer

 A mobile batching plant mixer functions as the mixing unit of a mobile plant. There are two types of mobile batching plant mixers: JZM self-falling concrete mixer and JS series twin shaft compulsive concrete mixer. Each type corresponds to different models of mobile batching plants.

The JZM series concrete mixer is a self-falling drum mixer, suitable for general construction sites, roads, bridge projects and small and medium-sized concrete component factories. The self-falling concrete mixer requires low power, novel structure, advanced performance, high production level, uniform mixing, compact structure, simple operation and maintenance, small size, and convenient mobile operations. Due to the special lifting drum mixing form, the lifting hopper of the JZM friction drum concrete mixer has a special lifting motor. During fixed mixing, a pit can be dug to make the hopper mouth flush with the ground, which is convenient for feeding and greatly reduces labor intensity. The roller of JZM series friction roller concrete mixer is driven by a rubber tug to drive the roller friction transmission. The models of JZM concrete mixer are JZM350 mobile type, JZM500 mobile type and JZM750 fixed type. JZM mixers are suitable for a drum mobile concrete batching plant, which are usually of small capacities like 25m3 and 35m3 per hour, the mixer equipped is JZM500 and JZM750.

The double-shaft forced concrete mixer has high working efficiency, large capacity and strong mixing capacity, which can fully mix the components of concrete evenly in a short time. This kind of mixer has good wear resistance, reasonable structure design, and can effectively prevent slurry leakage. It is a standard accessory for general mobile concrete mixing. During our construction and production of concrete, there are 7 types of more common compulsive concrete mixers, namely JS500 concrete mixer, JS750 concrete mixer, JS1000 concrete mixer, JS1500 concrete mixer, JS2000 concrete mixer, JS3000 concrete mixer, JS4000 concrete mixer. Among them, the first three are more frequently used for mobile stations, because the scale of mobile stations is generally not more than 75 square meters per hour. The mobile station is divided into wet mobile station and dry mobile station. Their configuration of concrete mixers is the same. For example, a yhz25 mobile dry type batching plant is equipped with a JS500 concrete mixer just as a wet 25m3 mobile plant.

 

Compulsory concrete mixers need more attention to maintenance and operating skills than free-falling mixers. The details are as follows: 1. Regularly lubricate the bearing parts according to the use situation. Refer to the product manual for the lubrication of the gearbox. 2. Regularly check the sealing condition of the machine, and check the quality of the gasket in time if there is any leakage. 3. Frequently check the fastening of the shovel blade, and tighten it in time if it is loose. Always check whether the electrical control system is in good contact and dry. 4. After long-term use of the mixer, the shovel blade and the mixing drum will wear out, adjust or replace according to the wear. 5. Do not insert your hands or sticks into the barrel during the mixing process to avoid danger.

Mobile batching plant with concrete pump

 A mobile batching plant with concrete pump may refer to a set of ready mix mobile concrete batching plant equipped with an extra pump, or a trailer concrete mixer pump.

A. Mobile concrete batching plant ready mix with a pump

This means a full set of mobile batching plant (drum or compulsive type) is equipped with a concrete pump of a capacity fully meeting the pumping requirement of the construction project. The plant models might be YHZS25, YHZS35, YHZS50, YHZS60 or YHZS75, and the concrete pump is usually a trailer pump between 20m3 to 120m3 per hour. The engine can be powered by diesel or electricity, but you have to choose the power type upon purchasing the pump, for these two types are not mixed in application. Generally both types are OK, and you just need to decide based on your local power conditions.

The advantages of such a set of plant include high automatic level, high efficiency and high concrete quality. Although the cost is much higher than simper types of mobile plants, it plays an irreplaceable role in big-scale construction sites that need concrete to be mixed and pumped efficiently.

B. Mobile concrete mixer with pump

This is one set of equipment rather than two like the plant and pump above. The plant here is composed of a trailer concrete pump and a drum mixer or twin shaft horizontal compulsive mixer, combining functions of both the pump and the mixer. In comparison to type A, this type of mobile batching plants consist of less devices and transfer more conveniently, and the cost is much less, too. However, it cannot compete with the former in either concrete quality or production efficiency, for its raw materials must be fed in a semi-automatic or totally manual way. Therefore, these plants are only suitable for small civil construction projects.

Haomei supplies both types of mobile batching plants with concrete pumps. Welcome to send inquiries!

hzs50 concrete batching plant cement silos - Haomei Machinery

 

How many cement silos an hzs50 concrete batching plant should be equipped with? What types of silos are the best for 50m3 concrete mixing plants?

　　Number of silos for hzs50 concrete batching plants

　　The number of cement bins of a 50m3 mixing station is not clearly specified, generally one or two, and there are also three. This depends on the cement label (whether fly ash, etc.), the type of admixture, the size of the cement bin, and the scale of the project.. If fly ash needs to be added to the concrete, the number of cement bins must be at least the same as the number of powders. There are also many types of cement silos depending on the storage capacity. Small ones are 30t, 50t, 80t, 100t, etc. These silos can be used with 50 concrete mixing plants. There are no specific regulations on which type of cement silo is matched with which type of small concrete mixing plant. Users can flexibly configure and select according to their own practical production needs. Concrete batching plant manufacturers usually provide a set of suitable options on the basis of understanding your needs at present and in the future.



　　Types of silos for hzs50 concrete batching plants

　　Horizontal cement silo: square, the bottom is supported by several legs, the discharge cone is a square cone, the silo is welded with a frame composed of corrugated cardboard and profiles, and the overall height is low. The horizontal cement silo production workshop is a complete set of production, no foundation installation on site, generally used for 50m3 mobile concrete plants.

　　Vertical cement silo: suitable for bulk cement and dry fly ash. It has the characteristics of rainproof, moisture-proof and easy to use, and it is configured for the standard cement silos of 50m3 concrete batching plants.

　　Assembled cement silo: also called flake cement silo, which is made into thin slices during production, which is convenient for transportation and used after assembly, especially suitable for export. However, the installation of the sheet cement silo is more complicated and the cost is higher. If you think that you choose a sheet cement silo, you must ensure that it can be installed smoothly.

　　Haomei is a professional supplier of concrete batching plants to Philippines, Indonesia, Malaysia, Australia, Thailand, Vietnam, Singapore etc. If you have more questions about cement silos, welcome to contact us!

Small cement pump price and operation tips

 　Small cement pump operation tips

　　The small concrete pump delivery pipe is not assembled with the whole machine. When used on site, it is configured according to different working conditions. The pipe layout is flexible and not restricted by height and length. Due to the high pumping pressure and severe vibration of small concrete pumps, the concrete conveying pipes are fixed on the ground or wall with supports. When pumping at high floors, due to the gravity of the concrete in the vertical pipes, it is necessary to prevent the concrete from flowing backwards. A section of horizontal pipe is arranged at the outlet of the horizontal pipe to balance the gravity of the concrete in the vertical pipe through the friction between the concrete in the horizontal pipe and the pipe wall, and a hydraulic shut-off valve is set at the junction of the vertical pipe and the horizontal pipe.

　　Small cement pump price

　　In fact, the price of a small cement pump depends on which model the customer needs for construction. If the construction project only has a head under 10 meters, then the LEB-10 type can meet the construction requirements. If the pumping head is greater than 10 meters, it is recommended to choose the LEB-30 type equipment. The motor power of the LEB-30 type small concrete pump is 15KW.

　　The working performance of the small concrete pump depends on the model. When purchasing and selecting models, in addition to considering the amount of pumped concrete, the type and structure of the building, construction technical requirements, site conditions and surrounding environment should also be considered. Under normal circumstances, the main performance parameters of the secondary structure transfer pump selected should be consistent with the construction needs, and there should be no too large gaps. Of course, when the pumping capacity is too large, the utilization rate will decrease and become smaller. This will cause delays in construction requirements. In severe cases, it will accelerate the loss of equipment.

Models and types for concrete batching plants

 　Concrete batching plant models

　　A concrete batching plant is a combined device for mixing concrete, also known as a concrete precasting plant. There are multiple models, including HZS25, HZS35, HZS50, HZS60, HZS75, HZS90, HZS120, HZS180, HZS240, HZS270. The size of the number represents The theoretical output of concrete per hour in the mixing plant. For example: HZS60 means that the mixing plant can produce 60 cubic meters of concrete per hour.

　　Concrete batching plant types

　　Different types of concrete mixing plants are divided into many categories according to different standards. The common classification standards are classified according to the purpose of use, which can be divided into commercial concrete batching plants and engineering concrete mixing plants.

　　Commercial concrete mixing plant is a concrete mixing equipment mainly for commercial purposes, which should be highly efficient and economical, while meeting environmental protection requirements. The engineering concrete mixing plant is for self-use, mainly considering whether it is consistent with its own project.

　　The specifications and models of concrete mixing plants are as follows:

　　HL: a concrete mixing building with one concrete mixer

　　HZ: a concrete mixing station with one concrete mixer

　　2HL: a concrete batching building with two concrete mixers

　　2HZ: a concrete batching plants with two concrete mixers

　　Models for concrete mixers:

　　D: single horizontal shaft type

　　T: planetary type

　　S: double horizontal shaft type

　　F: conical inclined discharge type

　　W: vortex type

　　Z: conical reverse discharge type

　　The main parameter code is productivity, in m3/h

　　Example: HZS180 concrete batching plant

　　⑴H-means concrete

　　⑵ Z—means a mixing station, if it is a mixing building, it is represented by the letter L

　　⑶S-indicates that the configured mixer (host) is a compulsory twin-shaft machine, if it is a compulsory single-shaft machine, it is indicated by the letter D

　　⑷180—It means that a 3m3 mixer can theoretically produce 3m3 ash per minute, and 60 ashing times per hour and 60 minutes. The corresponding concrete output is 3×60=180m3. If “2” is added before these symbols, it means that the configuration of the mixing plant is dual unit (dual line)

　　Types of concrete batching plants by capacity:

　　Small scale/Mini: HZS25, HZS35, HZS50

　　The production capacity of these several models of commercial concrete mixing plants is relatively small. The HZS25 type produces 25 cubic meters per hour, HZS35 produces 35 cubic meters per hour, and HZS50 produces 50 cubic meters per hour.

　　Medium scale: HZS60, HZS75, HZS90

　　The production capacity of these several models of cement mixing plants is relatively large compared to small commercial concrete mixing plants. HZS60 produces 60 cubic meters per hour, HZS75 produces 75 cubic meters per hour, and HZS90 produces 90 cubic meters per hour.

　　Big scale: HZS120, 2HZS120, HZS180, 2HZS180

　　Large concrete mixing plants have HZS120, double HZS120, HZS180, and double HZS180. The production volume is still the number behind HZS, but double HZS120 and double HZS180 are composed of two single commercial mixing plants, so the production volume should be doubled. There are many types of commercial mixing plants, the small one is HZS25, and the current large one is HZS270. HZS25 produces 25 cubic meters of concrete in an hour, and HZS270 is a mixing plant that produces 270 cubic meters in one hour.

　　How to choose models and types of concrete batching plants?

　　This requires the customer to do market research in advance, determine the demand for concrete within a certain range, and then choose the concrete mixing plant model with the appropriate output according to the local demand for concrete and the degree of competition.

Are ordinary and drum mobile concrete batching plants the same

 When we speak of mobile concrete batching plants, we usually refer to plants with modular units pulled by a trailer. As a matter of fact, there are two types of mobile batching plants, ordinary pants and drum mobile plants. The two have similar structures, the main difference lies in the type of concrete mixer.

An ordinary mobile batching plant is also called a compulsive mobile plant, for it’s equipped with a JS series twin shaft compulsive concrete mixer which is composed of feeding device, mixing device, water supply device, unloading device, oil supply device, and electrical control system. Models matching mobile plants include JS500, JS750, JS1000 and JS1500. A forced mixer can mix ordinary concrete, lightweight concrete and mortar, suitable for the concrete laboratory of scientific research departments, construction units, commercial concrete mixing plants, concrete and cement products industries, construction education and other units.

A drum mobile concrete batching plant, on the other hand, is equipped with a JZM concrete mixer. The JZ series are all self-falling concrete mixers, mixing in forward rotation and discharging in reverse. JZM stands for friction transmission. The models of JZM concrete mixers are JZM350 mobile, JZM500 mobile and JZM750 fixed. A drum mixer is installed on the mixer platform, and various metering devices are installed on the top of it. The amounts of cement, water, plasticizer, etc. are weighed according to the proportions. After the weighing is completed, they are discharged into the mixer and the weighed aggregates Stir together. The roller mobile mixing station is equipped with an aggregate batching device and a belt conveyor for conveying sand and stone aggregates. The head and bracket of the belt conveyor are set up on the aggregate storage, and the aggregate pre-feeding hopper (stores the mixed and weighed aggregate). They discharge the aggregate weighed in proportion to the concrete mixer.

 

The unloading height of drum mobile concrete batching plants is relatively low. Generally, the unloading adopts a high position of the whole station, which has a certain drop from the concrete tanker. And the efficiency of a drum plant is lower than compulsive ones. However, as a type of mobile concrete batching plant mini, drum plants are even more popular in various small construction sites.

How to modify control system of a concrete batching plant

 The control system of concrete batching plants has a life cycle. Generally, most of the electrical components will age after 4 to 5 years of use. The price of the control system before the modification is much cheaper than the brand new control system after the transformation. Some people would choose to remould part of the system, while others believe it’s better to replace all the parts of the old system.

　　The old-fashioned concrete mixing plant control system is divided into semi-automatic and fully automatic types. Generally, the old-fashioned automatic mixing plant control system needs to be partially modified, and the old semi-automatic centralized control system adopts full modification. At present, a small concrete batching plant for sale is still equipped with semi-automatic systems. After a period of use, they will still need to be modified.

　　Partial modification refers to the replacement of some parts, and replacement of some aging parts that cannot be used normally, such as board cards, plc modules, etc. The advantage is to save money; the disadvantage is that some components may have incompatibility problems. Generally speaking, the centralized control system with a service period of 2 years is recommended to be partially modified.

　　The entire transformation is to directly replace the original cumbersome manual button operation/low-automation control system with a mixing station system with a high degree of automation, weighing, and weighing speed. In addition, the power distribution cabinet line is changed, which makes the original messy thread ends assembled and replaced with a PRC line, so that the replacement is more thorough. The advantage of this approach is that the entire system runs smoothly, is compatible, and supports later function expansion; the disadvantage is that it requires more investment.

　　Due to the different transformation methods and the different specifications and models of the concrete batching plant itself, the transformation cost of the control system is not fixed. It is worth noting that the transformation cost of a compact concrete batching plant is not necessarily less than that of a commercial mixing plant, because although a compact plant is small, it has all necessary parts. The price of each part of its control system is not necessarily lower than that of a large mixing plant.

Conveying parts of concrete batching plants

 A stationary or mobile batching plant is a combined device used to mix concrete in a centralized manner, used in large and medium-sized water conservancy, electric power, bridge and other projects with large concrete works, long construction periods and concentrated construction sites. Among all the units of a concrete plant, conveying parts play a crucial rule. They function to send raw materials of given ratio and weight to the concrete mixer. Four parts might be applied in a concrete batching plant.

Belt Conveyor

The belt conveyor is used for transporting aggregates, fine aggregates, and used for mixing plants with a spacious site and a high degree of automation. The basic components are frame, conveyor belt, drive roller, modified lower roller, idler roller, driving device, etc. In some cases, cleaners, anti-deflection devices, feeding devices, unloading devices, braking devices, backstops, etc. may also be installed. A belt conveyor is applied in stationary plants over 60m3 and all mobile plants, even though it is a concrete mobile batching plant 25m3.

Bucket Elevator

The hoisting bucket should be hauled by a pulley block and steel wire rope with a brake hoist to achieve the purpose of lifting the hopper. In large and medium mixing plants, double steel wire rope transmission is often adopted; in small mixing plants, suspended single rope transmission or single rope transmission guided by a movable pulley on the hopper are mostly used directly. It can lift a variety of raw materials and is mostly used to lift mixed materials such as fly ash; in two-stage mixing plants, bucket elevators are also commonly used in collecting hoppers, and bucket elevators are generally used for small concrete batching plant production lines.

Screw Conveyor

The screw conveyor is the main equipment for conveying cement and fly ash. The rotating screw blade pushes the material to be conveyed by the conveyor. The force that prevents the material from rotating with the conveyor blade is the weight of the material and the conveyor. The frictional resistance of the shell to the material. It is mostly transported in closed pipelines, which is less affected by the outside world and can ensure the quality of materials. Belt conveyors are used in the production line of large concrete mixing plants.

Pneumatic conveying pump

The pneumatic conveying pump mainly uses compressed air to transport cement and fly ash from the bulk cement truck into the silo.

 

Each part of the conveying system play an indispensable rule in normal operation of a concrete plant. Some of them are also wearing parts. Purchasers are advised to ask stationary and mobile concrete batching plant manufacturers for spare parts if necessary.

Sizes of concrete boom pumps

 Concrete boom pump sizes include length, width and height of the chassis, pump arm height, boom section number, boom diameter size etc.

　　The length of a truck mounted concrete boom pump has various specifications, namely 21 meters, 24 meters, 28 meters, 30 meters, 33 meters, 38 meters, and 35 meters. Different pump trucks will be designed according to the requirements of the length, width and height of the chassis, the efficiency requirements of the mixer, the length of the boom, etc. For example, under the condition that the other configurations of the 33-meter pump truck remain unchanged, the boom design is optimized and the overall layout is adjusted Then launched a 35-meter mixing pump truck.

　　According to the height of the boom of the pump truck, a concrete boom pump can be divided into short boom, long boom, and super long boom. Usually the boom length of 13-28 meters is a short boom, 31-47 meters is a long boom, and 51-62 meters is an ultra-long boom. The most common pump trucks currently on the market are mostly short boom and long boom.

　　According to the different number of boom sections, concrete boom pump trucks can be divided into four types: 2 boom, 3 boom, 4 boom, 5 boom, 6 boom, 7 boom. The most common ones in the market are 2-section arms, 3-section arms, 4-section arms, and 5-section arms. The maximum height of the 5-section boom 4-axle boom is between 50 meters and 56 meters. The size of the pump tube is 125MM.

　　The low pressure type of the pump pipe is a pipe with an outer diameter of Φ133, and the high pressure is a pipe with an outer diameter of Φ140; the low pressure model of the 150 type pump pipe is a pipe with an outer diameter of Φ159, and a high pressure is a pipe with an outer diameter of Φ168. The head of the pump pipe is a specially processed pipe joint, which is connected to the pipe body by welding, and the connection of each pipe is connected by a pipe clamp processed by a precision casting process.

HZS35 semi automatic concrete batching plant

 

　　As a kind of mini concrete plant, hzs35 concrete batching plant is generally equipped with a semi-automatic mixing system. The main difference between fully automatic and semi-automatic concrete mixing plants is the control system, and the other equipment is basically the same. Both include storage, conveying, weighing, mixing and control systems, and the work flows are also very similar, divided into four parts: sand and gravel feeding, powder (cement, fly ash, expansion agent, etc.) feeding, water and admixture feeding, transmission, mixing and storage Specifically, the material (mainly stones of various sizes) is introduced into the batching machine with a loader for classification and weighing. The weighed sand and gravel are sent to the mixer by the belt conveyor. At the same time, the powder in the powder silo is weighed and enters the mixer through the screw conveyor. Water and admixtures are also weighed first, and then pumped into the mixer. So far, all kinds of raw materials are ready. The mixer starts to work. After the mixing is completed, the unloading door is opened, and the precast concrete falls into the waiting concrete truck (usually a concrete mixer).



　　So, what is the difference between a semi automatic concrete batching plant and a fully automatic concrete batching plant? To put it simply, it is fully automatic that you set up the program on the computer in advance, and then watch the mixing station complete the work process step by step; semi-automatic requires you to press buttons step by step to operate, for example, when the concrete is working to loading, just click Press the button for loading, then the materials will be automatically transported to the weighing hopper. When you need to unload, click the unloading button, and the materials will be automatically discharged into the mixer. The biggest difference between it and fully automatic is that it requires more operators. The advantage is that the cost is low, that is, it is cheaper when you buy it. The disadvantage is that the labor cost is high, that is, it is more expensive for you to use it.

　　Except for 35 concrete mixing stations, almost all batching plants can be equipped with semi-automatic systems, including hzs25, hzs50, hzs60, hzs75, hzs90 and even hzs120 and hzs180. However, in terms of the degree of use, commercial concrete mixing plants above 90m3 are generally not recommended to adopt semi-automatic systems, because the efficiency of the automatic mixing station is significantly higher, and it can better meet the needs of commercial mixing stations to pursue production efficiency.

Tips for run-in period of 50m3 mobile batching plants

 The newly purchased concrete mixing plant will have a running-in period, and an yhzs50 mobile concrete batching plant is of no exception. The main task during the running-in period is to inspect the operation and stability of the equipment, to understand the details of all aspects of the equipment, so that the concrete mixing plant can pass the running-in period smoothly and give full play to its maximum performance. The matters needing attention are as follows.

1. Pay attention to the work load control during the running-in period of the 50m3 mobile batching plant. The work load during the running-in period should generally not exceed 80% of the rated work load, and proper workload should be deployed to prevent overheating caused by continuous operation of the machine for a long time The occurrence of the phenomenon.

2. Operators should receive training and guidance from the manufacturer, have sufficient knowledge and understanding of the structure and performance of the machine, and obtain the corresponding operation and maintenance experience to operate the machine. The product manual provided by the manufacturer is the necessary information for the operator to operate the equipment. Before operating the machine, be sure to browse the manual for the concrete mixing plant, and operate and maintain according to the requirements of the manual.

3. Pay attention to frequently check the use of lubricating oil, hydraulic oil, coolant, brake fluid and fuel oil (water), and pay attention to check the sealing of the whole machine. In the inspection, it is found that the oil consumption is insufficient and the reason should be analyzed. At the same time, the lubrication of each lubrication point should be strengthened. It is recommended to add grease to the lubrication point during the running-in period.

4. Pay attention to frequently check the operation of each instrument. If any abnormality occurs, stop the machine and eliminate it in time. If the cause is not found, the operation should be terminated immediately before the failure is eliminated.

 

A YHZS50 mobile mixing plant equipment includes twin-shaft mixer, batching machine, cement silo and screw conveyor, computer control room. It adopts JS1000 twin-shaft forced mixer, which is a compulsory and high-efficiency equipment. It can produce plastic and dry concrete and other concretes. It has high production efficiency, short mixing time and beautiful appearance; the batching machine is PLD1600, batching Accurate and fast response, which can be adjusted according to user needs. Because of the small space occupied, the amount of capital occupied, and the production efficiency higher than a general mini mobile batching plant, the yhzs50 concrete batching plant has become an ideal model for bridge construction. If you can pass the running-in period safely, 50 plants will bring you high profits.

Solution to rotating failure of concrete pump truck arm

Example: A 2006 37-meter concrete boom pump truck suddenly appeared close to the boom during the pumping process. In the remote control state, the left and right sides can only be rotated unilaterally or neither side can be rotated.

　　Failure analysis

　　1. Electrical aspects:

　　(1) Whether the boom rotation limit switch is damaged

　　(2) The power status of the rotary solenoid valve of the boom and whether it is damaged

　　(3) Whether the relay is damaged

　　2. Hydraulic:

　　(1) Valve block problem of boom rotating multi-way valve

　　(2) Problem of boom rotating balance valve

　　(3) Reducer motor failure

　　(4) The reducer is damaged

　　Troubleshooting process:

　　1. Electrical:

　　(1) Check whether the I2.6 and I2.7 lights are on. If they are not on, it means that the boom rotation limit switch is not damaged. If it is lit, we disassemble the corresponding wiring to see if the fault remains: normal, it means that the limit proximity switch is damaged. If it remains, it means that the proximity switch is damaged and there are other faults.

　　(2) Check whether both solenoids are energized or not when the boom rotating solenoid valve is not rotating. Check whether Q3.0 and Q3.1 have output (check whether there is voltage output on lines 69 and 70 of the action boom). There is no output. Check whether the K31, K32 relays and modules are damaged. There is output, but the solenoid valve is not energized. Check whether there is a problem with the disconnected circuit. The solenoid valve is energized, check whether the resistance of the solenoid valve is normal, and the coil of the abnormal solenoid valve is damaged.

　　(3) Check whether the spool of the rotary solenoid valve is normal. Apply 24U voltage to the solenoid valve to see if the spool is moving. There is no action and the spool is damaged.

　　(4) If the electrical aspect is normal, perform hydraulic analysis

　　2. Hydraulic:

　　(1) Check if the multi-way valve head is damaged, and exchange the tubing with the No. 1 boom multi-way valve to see if there is no action when rotating. If there is a proof of the multi-way valve head problem, see if the orifice inside is blocked.

　　(2) Check the rotating balance valve and clean the spool to see if the card is issued.

　　(3) Check the hydraulic motor to see if it can rotate or not, the motor is damaged.

　　(4) Disassemble and inspect the reducer to check whether the bearing inside is damaged, and replace the bearing.

　　l After inspection, the fault of this boom concrete pump truck is that the coil of the rotating solenoid valve is burnt out. After replacing the solenoid valve, the equipment is normal.

　　Summary: Single-turn or non-rotation of the boom is a common fault of the boom-type pump truck, which generally appears in the electrical aspect. Therefore, first from the electrical to the hydraulic, the fault can be quickly eliminated from the easy to the difficult.
