When buying a new concrete batching and mixing plant for the first time, some customers will encounter wear and tear problems and will be very distressed. According to the analysis of relevant technical personnel, the reasons for the failure of the newly built concrete batching plant are as follows:

1. Parts damaged by friction caused by rough surface of new concrete batching and mixing plant parts. Under the influence of factors such as processing, assembly and adjustment of new mechanical parts, the friction surface is rough, the contact area of the mating surface is small, and the pressure resistance state of the surface is uneven. When the machine is running, the concave and convex parts on the surface of the parts mesh and rub against each other, and the metal chips that fall like abrasives continue to participate in the friction and further accelerate. Wear on the mating surfaces of parts. Therefore, the wear of parts (especially the mating surface) is prone to occur during the running-in period, and the wear rate is high. If overloaded at this time, parts may be damaged and premature failure may occur. example:

2. The fitting clearance of the newly assembled parts of the concrete batching and mixing plant is small. Due to assembly and other reasons, the improper use of the lubricant between the various parts of the concrete batching and mixing plant will cause the new parts to wear out. It is difficult to ensure the uniformity of the fitting clearance, and it is not easy to form on the friction surface. A uniform oil film prevents wear. As a result, lubrication efficiency is reduced, and premature and abnormal wear of parts occurs. In severe cases, the precision-fit friction surfaces may be scratched or blocked, leading to failure.

3. Loose parts will affect the normal operation of the machine. The newly machined assembly parts of the concrete batching plant have deviations in geometry and matching dimensions. At the beginning of application, due to factors such as thermal deformation, the original tightening parts are due to excessive wear and other reasons, as well as alternating loads, such as Shock and vibration as well as heat and deformation. This will loosen easily.

Users can refer to the instruction manual when using the concrete batching and mixing plant, and know that the mixing plant must be well maintained and cannot be overloaded. Only in this way can the concrete batching plant be used efficiently for a long time.
