Quality appraisal of mobile crusher

mobile crusher is a device used to crush various stones and construction waste, which is mobile and efficient. It can be flexibly moved between different construction sites and is suitable for road construction, bridge construction, mining and other fields. The working principle of
mobile crusher is to feed the raw materials into the crusher through the feeder. The crusher breaks the raw materials into the required particle size, and then transports the crushed materials to the target location through the conveyor belt. Finally, it is screened through the vibrating screen to separate materials of different particle sizes.
In the case of mobile crusher quality appraisal, Zhongke Testing can provide mobile crusher quality appraisal services.

1, equipment deformation and cracking: This problem is usually caused by poor material quality, poor workmanship, or excessive impact during work. Equipment deformation and cracking will cause the equipment to fail to work properly, and may even endanger workers' safety.
2. Oil pump failure: The hydraulic system in the mobile crusher is very important, and the oil pump is one of the core components of the hydraulic system. Oil pump failure may cause the equipment to lose power and control capabilities and fail to work properly.
3. Electrical problems: The electrical part is another important part of the mobile crusher. Its failure may cause the equipment to fail to start or stop working. Causes of electrical problems may include shorted wires, failed switches, power issues, and more.
4, wear and aging: Mobile crushers need to withstand heavy loads and high-frequency vibrations during work, which will cause wear and aging of components and parts in the equipment. These problems can cause the device to lose precision and control.

A mining company purchased a set of mobile crusher equipment. During later use, the equipment experienced problems such as deformation and cracking, which eventually led to the failure of normal operation. Therefore, the mining company took the seller, a machinery and equipment manufacturing company, to court and demanded compensation.
was entrusted by the court to conduct an appraisal and analysis on "whether there are quality problems" with the mobile crusher involved in the case.
appraisal analysis results: The
appraisal analysis expert group discussed and conducted comprehensive quality and technical analysis on the relevant information and on-site investigation of the mobile crusher involved in the case, and made the following suggestions and conclusions:
The mobile crusher involved in the case has serious quality problems, causing it to be unable to work properly.
