Author: Time:2018-10-25
Due to the long-term operation in the harsh working environment, the jaw crusher needs to crush ore, cement, stone, etc. with high hardness, so the wear is extremely great, the replacement frequency of wear parts is high, and spare parts need to be prepared to avoid delay in production, which involves Disassembly of the jaw crusher.

The most frequent replacement of jaw crushers is the thrust plate, the toggle plate. The crusher of the integral connecting rod must be removed from the thrust plate. First unscrew the baffle bolt, cut off the dry oil lubricating pipe, and hang the thrust plate on the crane lifting hook or other lifting equipment before releasing the horizontal tie rod. The spring at one end pulls the movable jaw in the direction of the fixed jaw and takes out the thrust plate. If the thrust plate is to be removed, the connecting rod should be pulled apart from the front thrust plate and the moving jaw, and the rear thrust plate should be taken out.


After the thrust plate is removed, cut off the thin oil lubrication pipe and the cooling water pipe, support the bracket under the connecting rod, and then remove the connecting rod cover to lift the connecting rod.

The main shaft of the crusher should be removed together with the pulley and the flywheel. Move the motor (along with the belt) along the slide rail as far as possible to the crusher and remove the V-belt. Then lift the shaft with a crane.

In order to disassemble the moving boring, the dry oil lubricating oil pipe must be cut off, the tie rod should be disassembled, the bearing cap removed, and then the crane pulled out with a crane or other lifting equipment.
