Hubei crusher is widely used in various industries, especially in mining industry. Because of the different uses, jaw crusher can be divided into laboratory jaw crusher, mining jaw crusher and other models of different uses. The laboratory jaw crusher is generally small in size and easy to use. In the process of using various crushers, operators should pay special attention to the maintenance of the equipment.

During the maintenance, the operator should stop the machine regularly and check the machine. Any stone crushing equipment shall be shut down regularly to check the internal wear of the machine, especially the wear degree of the central feeding pipe, cone cap, upper and lower runner liners of impeller, peripheral guard plate and wear-resistant block. The operator shall replace the parts with serious wear in time and repair these parts. Special attention shall also be paid to the lubrication of each component. When the equipment works for more than 2000 hours, the operator shall open the spindle assembly to clean the bearings. In general, replace the bearing after 7200 hours of operation.

In addition, the drive belt of Beijing E crusher should be checked regularly. The ezuo conveyor belt is indispensable in stone production line. The driving of the machine is due to the conveyor belt. Adjust the tightness of the conveyor belt regularly to ensure that the force on the conveyor belt is even. In case of double motor driving, the triangular tapes on both sides shall be selected in groups to make each group as long as possible. If it is found that the wear degree of the drive belt is too serious, it should be replaced in time to avoid more serious consequences. In order to ensure the normal operation of jaw crusher, in addition to the correct operation of jaw crusher, it is necessary to carry out planned maintenance, including daily maintenance, inspection, minor repair, medium repair and overhaul.
