Due to long-term operation in harsh working environment, jaw crusher needs to crush high-hardness ore, cement, stone, etc., so it is extremely worn and the wear-resistant parts are replaced frequently. Spare parts need to be prepared to avoid delay in production. This involves The disassembly problem of the jaw crusher.

The thrust plate, which is the toggle plate, is the * frequently replaced jaw crusher. For crushers with integral connecting rods, you must remove the thrust plate, * unscrew the baffle bolts, cut off the dry oil lubricating pipe, hang the thrust plate on the crane hook or other lifting equipment, and then loosen the horizontal tie rod The spring at one end pulls the movable jaw to the direction of the fixed jaw and takes out the thrust plate. If you want to take out the rear thrust plate, you should pull the connecting rod, the front thrust plate and the movable jaw together, and take out the rear thrust plate.

After the thrust plate is removed, cut off the thin oil lubrication pipe and the cooling water pipe, support it with a 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 flywheel, move the motor (along with the belt) along the slide rail as close as possible to the crusher, and remove the V-belt. Then lift the shaft with a crane.

In order to disassemble the movable jaw, you must * cut off the dry oil lubricating pipe, disassemble the tie rod, remove the bearing cap, and then use a crane or other lifting equipment to pull the movable jaw out.
