Maximum pumping height of a 45m concrete pump truck

 The maximum pumping height of a 45m concrete pump truck is generally over 40m, although different manufacturers offer varied figures. Generally the vertical pumping distance of a pump depends on the length of its pumping arm, the rear two pieces of which usually cooperate to pump concrete. The biggest pumping height of pump trucks in China proves to be 411m, realized in 2008 by a Zoomline truck with a power of 572kw.

Essentially the pumping height is up to the motor power of a concrete pump truck. The stone of the pumped concrete is mixed with different particle sizes and different ratios, that is, aggregate gradation. The combination of sand and stone in a certain ratio is the sand rate. A certain amount of cement, fly ash, mineral powder, water, etc. are added during mixing to ensure that the mixed concrete has good workability and fluidity. It ensures that there is enough mortar wrapped around each aggregate. Under the pressure of the concrete pump, the principle of liquid incompressibility is used to push the concrete pump to a high place.

 

Therefore, you can just attach soft tube to the pumping arm if necessary. According to the pumping pressure, the attenuation of the pumping pressure in the pipeline is 0.133 kPa per meter. A 90-degree elbow is equivalent to the resistance of a three-meter straight pipe, and a three-meter hose is equivalent to the resistance of a twenty-four-meter straight pipe. It is impossible to maintain the normal pumping pressure to be less than twelve. You can calculate how many meters of hoses can be added based on the motor power of your 45m concrete pump truck. Pay attention to the thickness of the pipe, the quality of the sealing ring, the gap of the cutting ring of the eye plate, etc.

Why is mobile concrete batching plant price higher than stationary plants

 

　As known to all, the mobile concrete batching plant price is usually higher than that of stationary plants of the same capacity, whether you purchase at home or from abroad. In addition to the increasing demand of mobile plants in road construction, the structure and equipment of a mobile plant also contribute to its higher cost.



　　The structure of a mobile concrete batching plant is quiet compact. The chassis integrates the mixing station into a whole, which is moved by tires. Except for screw conveyors and cement bins, the entire front end of the mixing plant can be towed and moved. Other control cables such as walking platforms and heightening boards do not need to be disassembled for transportation. A new mobile plant is easy to be shipped, too. The whole plant takes up only three 40 feet containers. There’s no need of civil engineering for a mobile plant, for it’s equipped with a fixed supportive platform. And the floor space is smaller as well. The control system of a mobile batching plant is more intelligent, stable and reliable. It has multiple auxiliary functions such as replenishing scale, buckling scale, continuous production, and intelligent alarm. It can realize automatic mixing operation. You can see the real-time production status of each mixing station module through the screen, and manual interruption of the weighing process is acceptable in operation. In addition, the wear parts of a mobile plant are far less. This benefits from adoption of new anti-wear technology, which partly leads to the rise in plant price.

　　An extra vehicle also adds to the price of a mobile plant: trailing machine. At present there are two types of trailing machines: tow type and trailer type. The towed chassis includes a complete front rear axle; the trailer chassis only has the rear axle, and the front end is located on the tractor's saddle bridge. Either type is excluded in a stationary plant.

　　The reasons above account for a higher mobile concrete batching plant price in comparison with a stationary one. With rapid development in technology, the price might be reduced in the future.

How to choose asphalt mixing plant manufacturers in China

 To choose reliable China asphalt mixing plant manufacturers, you should focus on 5 aspects as below.

The first is the credibility of the asphalt plant manufacturer. Credibility is the first face of an asphalt station manufacturer, as well as its first impression on the market and customers. You can learn the reputation of manufacturers through multiple channels, including the Internet, friends, peers, etc. Second, you can learn about the history of these manufacturers. The establishment time can best explain the market competitiveness of a manufacturer. In addition, you can understand the strength of an asphalt mixing plant manufacturer through its certificates and profiles, website, and the maturity of its market scale. Third, look at the management level of an asphalt mix plant manufacturer. In addition to the experience of the workshop and factory facilities, you can be more careful. Sometimes a small detail can reveal management problems. Fourth, after-sales service. For asphalt mixing plant manufacturers, you may be most concerned about the availability of their technical guidance and maintenance services, as well as the efficiency of their service. These can all be understood directly from the sales staff.

 

Last but not least, you should compare the technical strengths of different asphalt mixing plant manufacturers, which mainly includes the advanced level of production equipment, the number and ability of engineers, and the ability of equipment operators. Advanced production equipment is a hard target, which must meet the characteristics of complete, new and refined, so as to meet the needs of producing high-quality asphalt mixing plant equipment. The number of engineers implies the actual technical capabilities of a manufacturer. An excellent team of engineers can not only greatly expand the production capacity of a factory, but also greatly reduce production costs and improve machine quality. The operating ability of equipment personnel is the ultimate guarantee. The professional technical ability and personal ethics of operators are the key to the quality of an asphalt station. This technical capability includes the degree of understanding of the product process and the degree of mastery of the equipment performance, which must be completed after a long time of accumulation. Therefore, you can inquire about the working years of the workers in any possible ways.

Concrete batching plant capacity in China

 Concrete batching plant capacity in China is directly associated with the number of its model, including 25m3, 35m3, 50m3, 60m3, 75m3, 90m3, 120m3, 180m3 etc. And there are some exceptions. Take SHZS120 for example. Pay attention to the letter “s” here. This letter means “double”, indicating two HZS120 plants working cooperatively, thus its capacity is doubled, too, namely 240m3 per hour.

But usually the real capacity can not reach the given capacity. The number in the model of a concrete plant, either stationary or mobile, stands for only the theoretical capacity of the plant. The actual production volume often drops behind it, for even a perfectly designed concrete mixing plant can not avoid being influenced by external influence in real operation, like weather conditions, concrete delivery state, concrete demand, operating problems or management failures. Therefore, it’s almost impossible for a ready mixed concrete plant reach its theoretical capacity in practical production.

 

Nevertheless, we can still do something to enhance the real productivity of a concrete batching plant china. First, arrange delivery vehicles in a more reasonable way. It’s not enough to take account of concrete batching plant capacity, delivery distance, delivery route and road conditions while calculating the number of concrete mixer trucks you need. You should equip two extra trucks for ten to deal with unexpected incidents. Second, appoint a reliable manager whose capability and attitude will have direct impact on the operation state of the support equipment as well as the concrete batching plant itself. Third, pay attention to sufficient raw material supply, regular concrete batching plant maintenance and necessary stock of ready mixed concrete. Forth, take good care of raw materials on rainy, windy and snowy days. These steps not only make the concrete production process smoother but also help tackle common accidents, guaranteeing normal operation of the batching plant and improving its actual capacity.

Concrete batching plant price

 

　Concrete batching plant price ranges between $20,000 to $2,000,000 per set, depending on the capacity, configuration, accessory brands of the plant and the production cost of the supplier.



　　The capacity of concrete batching plants can be 20m3 to 240m3. The smallest plant has the simplest configuration, maybe only a self-falling concrete mixer, a weighing system and several people feeding ingredients to the mixer. A large standard commercial concrete batching plant, on the other hand, might be composed of a whole set of machines, devices and vehicles, including not only concrete mixers, but also belt conveying devices, silos with screw conveyors, batching machines, fully automatic control systems, concrete mixer trucks and even concrete pumps. These parts might be of the best quality to guarantee production efficiency and reduce maintenance cost. As a result, the latter can be thousands of hundreds of dollars more expensive. In addition, mobile plants cost more than stationary plants, for they must be equipped with towing trucks and other necessary accessories.

　　If you need plants of top quality and stability, superior components will be applied, which means higher investment in raw material. Some factories import all accessories from Germany and Italian to guarantee the quality of its plants. This will help them to provide plants of reliable property, but the prices will rise correspondingly. A cleverer way is to import key components of high technology, and produce other parts by themselves. Some units, like silo pieces, belt rollers and batching machine hoppers, are of low technological level as long as you select excellent raw material. This alone will help to reduce the production cost substantially. Therefore, not all cheap concrete batching plants are necessarily of poor quality. However, you must bear in mind that the price of a plant always matches its quality, and that it’s impractical to pursue extremely low prices and good quality at the same time.

Concrete batching plant price in china

$20,2000 to $1,000,000 based on varied configuration

Purchasing Advice

1. Matching equipment. For example, the loading capacity of the mixer truck should match the discharging capacity of the mixer, and the loading capacity of the loader should match the loading height of the batching station of the concrete batching plant.

2. The production scale determines the basic model of mixing plant. Calculate the daily maximum output through the annual output, and then accurate to every hour, which is the model you want to choose. If the annual output is less than 200000 m3, the productivity of concrete mixing equipment is generally not less than 90m3 / h.

3. If the output of a batching plant is relatively large, concrete mixing plant or concrete mixing building can be selected. The former has neat and beautiful overall shape, small area of stockyard, good production environment, long manufacturing and installation cycle, and high one-time investment cost. The latter has flexible layout, short delivery period and low price, but it covers a large area and has air and noise pollution.

4. The accessories of the equipment should be standard parts for later maintenance. Large scale concrete mixing plant can be configured with network management function to avoid difficulties in future upgrading.

5. Whether the supplier's ability in installation and debugging, technical guidance, after-sales service and spare parts supply meets your needs.

 

7. Price choice: avoid excessive pursuit of equipment technical performance and increase unnecessary investment, and avoid pursuit of low price and reduce equipment technical performance. In China's concrete batching plants, imported components are widely used in the key parts, and the overall performance is not worse than that of all imported components
