Failures Analysis

When the vibrating screen is in the normal working status, if the rotation is slow and the bearing has a high temperature, which show that the work of usual maintenance needs improving and the lubricants are needed. Routine maintenance is also very important. If the lubricant on the bearing is newly added, the problem maybe lies in the poor quality of the lubricants or adding too much on the bearing lubricants. The lubricant with poor quality will block the bearing and labyrinth seal. Therefore, the quality of lubricants is critical. The reasons for the poor screening quality may be the improper use or the blocking of the mesh. The increase of the fine-coarse-grained materials and moisture will result in that the material layer is too thick and the feeding is uneven.

As for the vibrating screen itself, the both sides of the sieve is not tight. If there is much noise in the screening process, the reasons maybe include that the bearing is damaged, the bolts loose, the breaks and the spring is damaged crossbeam. In addition to the bolt that can be tightened, the parts should be replaced in other three conditions. In view of the above failures, we can reduce the failure rate through routine maintenance. Before the starting up of the machine, checking the oil level of both sides. If the oil level is too high, which will lead to problems or the temperature of exciter rise operation; If the oil level is too low, which will cause the bearings to be prematurely damaged. Checking all bolts to ensure that all of them are tightened and after working for eight hours, re-tighten them.

Checking the tension of the V-belt to prevent slip at the start or work. Making sure the minimum clearance between all moving parts and fixtures. The feeding can not be conducted until the sieve is running smoothly to make sure the sieve works without load and before stopping the machine, it is necessary to clean the materials on the sieve surface. In short, summarizing the failures of mine vibrating screen is to prevent and reduce the occurrence of the failure. If the failure emerged, we can timely settle them to minimize the impact on production. Rock crusher cone: ball mill:
