The jaw plates of the jaw crusher are divided into fixed jaw plate and mobile jaw plate,which are the wear parts of the jaw crusher.Because the working environment is poor, in the using process,the jaw plate sustains the plastic deformation wear and the cutting wear, the wear is quite serious.Only by strengthening daily maintenance of the jaw plate can reduce wear and improve the work efficiency.This article will show a few maintenance methods for the jaw plate of the jaw crusher in order to increase its service life.
If you find that the jaw plate wears out eiously or the front plate is broken, you should take the repair measures to take the ores out of the crushing cavity , remove the grinded or the broken jaw plate and check whether the mobile jaw and the rod on the bracket are damaged or not.For the worn jaw plate, the welding method can be employed to heal the tooth.
Carry on the sampling inspection for each batch of materials feeded into the machine .When you find the a significant fluctuation of the properties of the materials , adjust all main parameters of the crusher,such as clamp angle, eccentric shaft rotation speed, capacity and power of electric motor,etc,so as to make the machine adapt to the materials to reduce the wear of the jaw plate.
Pay attention to fasten the newly installed jaw plate , and ensure that the contact surface of the jaw plate and the body (fixed, fixed, e)is smooth.Pad a layer of materials which has good plastic performance,such as lead plates ,plywood and cement mortar,etc, between the two surfaces .The assembly requirement of the mobile jaw plate and the fixed jaw plate is that the teeth peak of one jaw plate aligns the teeth slot of another jaw plate , namely,the mobile jaw plate and fixed jaw plate are in the basic meshing state.
