Concrete mixer truck dimensions and capacity

图片
Concrete mixer truck dimensions and concrete mixer truck capacity are two different concepts, but not a few people who are not from English-spoken countries confuse them. Here is a detailed explanation.   The  concrete mixer truck  capacity  refers to the tank volume of a concrete mixer truck. Such a truck mainly consists of two parts: the upper part (mixer tank and other smaller components like water tank and motor) and the chassis. And capacity here equals the volume of the mixer tank, usually measured by the unit of cubic meters. Regular capacities for a ready mix concrete truck include 3m3, 4m3, 5m3, 6m3, 8m3, 10m3, 12m3, 14m3, 16m3 and 18m3, among which the first four are regarded as capacities for small mixer trucks and the latter ones large trucks. 3m3 to  6m3 concrete mixer truck s are applied in narrow construction sites like tunnel building projects, and 8m3 to 12m3 concrete mixer trucks are the most popular ones, the price of which is around 100 thousa...

Fully automatic cement brick making machine systems

It is necessary to provide practical and reliable bag type dust collection equipment or pulse dust removal equipment at the top of each powder silo, so that the dust emission concentration of the exhaust gas reaches the national discharge standard; In the stone yard, raw sand can be built into a semi-closed yard, sprinkling water on sand an...

Commissioning of a concrete batch mix plant

图片
After a concrete batch mix plant is built, the first step is to debug the operation, check the correctness and reliability of the mechanical and electrical system installation, and confirm the correctness before commissioning. The commissioning of a concrete batch mix plant equipment is divided into that for mechanical, electrical and mechatronics parts.   The debugging steps of a stationary or  mobile concrete plant  are as below:   1. Adjust the unloading door of the aggregate storage bin of the concrete mixing station, and each material door should be opened and flexible; start the flat belt electric drum, the belt running direction is correct, and there is no deviation.   2. Start the inclined belt, the belt runs in the correct direction, no deviation phenomenon, no abnormal sound.   3. Check whether the cement mixing bucket, the fly ash measuring bucket, the water and the admixture measuring bucket of the  hzs 25 mini mobile concrete batching plant  are...

How to dismantle a ready mix concrete batching plant

图片
It’s not recommended to move a ready mix concrete batching plant after it has been installed, but dismantlement is necessary after the construction work is completed. The power consumption does not mean that improper removal and installation may affect the subsequent use of the equipment. But there are some reasons for this or that that lead us to dismantle the concrete mixing plant. How do we ensure that the equipment is intact and reused during the demolition process? The dismantling of even a  mini batch mix plant  entail adoption of machines like a 70T truck crane (as a lifting device for demolition) and a 25T truck crane (as a dismantling and disassembly vehicle and on-site transfer handling vehicle). Specifically, the removal steps of a concrete mixing station are as below. 1. The outer color plates are removed, the peripheral color plates and skeletons are removed from top to bottom, and the cutting phenomenon is avoided during the process of removing the color p...

Reasons for pipe plugging of a trailer concrete pump

图片
Today, the use of trailer concrete pumps has been frequent, but blocking the pipe is still a problem for construction workers. Once the pipe is blocked, it not only damages the machine, but also delays the construction period and causes unnecessary waste. Today, we will talk about how to prevent the plugging of the pump.   First of all, we need to know what is the cause of the blockage of the concrete pump, so that we can find out the source and the right solution. There are five main reasons for the mixing of the drag pump:   1, the concrete material problem is the first factor that causes the dragging pump to block the pipe.   2. If the leaking of the duct is poor, the fluidity of the concrete will be poor due to the leakage of the cement slurry, and the friction will be large, which will cause the plugging of the  trailer concrete pump .   3. After the previous pumping is completed, the catheter is not cleaned according to the rules, which causes the catheter to ...

How to deal with truck mounted concrete pump failures

图片
There are many possible failures of a truck mounted concrete pump, and here we deal with several of them. Solutions are shared as well. The hydraulic  system  of a concrete pump truck is  without pressure or insufficient pressure . Reason: The relief valve is opened, because the valve core is stuck, it cannot be closed, the damping hole is blocked, the valve core and the valve seat are not well matched or the spring is invalid. Solution: repair the valve core and the housing, clean the damping hole, replace the spring Reason: Other control valve spools are stuck due to faults, causing unloading Solution: Find the fault location, clean or repair, and make the spool move flexibly in the valve body. Reason: The hydraulic components are seriously worn or the seal is damaged, causing internal and external leakage. Solution: Check the tightness of the connections at the pump, valve and piping, repair or replace parts and seals I nsufficient traffic  of t he hyd...

Judgement tips for a mobile ready mix concrete plant
