The vertical and horizontal directions of the dynamic and static jaw plates of the drive crusher mainly include cracks, breaks, wear of bearing holes, raising faulty materials, and loosening of connecting bolts.

Sand making is a common failure of crushers. The general law of sand making performance dimensions: To judge the good of sand making, clean the sand making, sand making treatment, and the place where the re-output is connected to the sand making cannot be removed, the test of the test can be preliminarily determined with white powder magnetic sand, and the mining method of the basic magnetic or magnetic test after the magnetic sand can be determined. Since the 5mm wide twist of the straight line of the cooked station in the sand making, the depth is 1.1 to 1.3 times greater than the depth of the sand making. Then use gas cutting to cut the sand making to cut the deep V-shaped groove, and then repair it correctly according to the soft material operation of the magnetic carbon. The worn longitudinal is repaired, and after welding, it is put back into the dummy state.

Breaking is also the fault of the drive plate failure. Generally, it occurs suddenly. After verification in actual production, the technical level of the broken part can be frequently found out from the prison, and it can be completely repaired. Before the speech, the general work should be done well, and the specifications of the speech should be repaired.

The wear of the bearing hole is mainly due to improper installation or unsatisfactory mechanical processing requirements. After the crusher has been running for a period of time, the wear of the bearing hole occurs. The treatment method is generally based on the welding repair processing method. After the repair welding of the grinding part hole is carried out, the basic size of the solid hole such as the building dragon is increased, and the main plate of the building is enlarged into the ruler to prevent the repair welding stress from causing deformation in the subsequent processing process. The drive crusher is a common equipment machine. It needs to be disassembled and assembled to break the weight of the application problem. In the target production, it is necessary to do flow operation, and the dynamic broken plate and the pole part of the solution plate are monitored at the measuring point to strengthen the maintenance technical level of the other solid treatment department to ensure normal production.
