Jaw crusher in grinder mill in the use process,often occur the phenomenon of jaw plate wear.What causes it?

The main reason for the jaw plate wear of jaw crusher in grinder mill is that, relative to the jaw plate,the materials do a short-range sliding,cutting of metal causing a repeated extrusion between the debris and the materials caused the jaw plate deform,led to the materials fall down,so results in jaw plate wear.This wear belongs to chisel cut-style wear.

This shows that the wear is mainly caused by debris.But how irt forms?

The repeated extrusion of the materials,causes the jaw plate or the surface of jaw plate prominent,the roots forms micro-cracks,the micro-cracks expand constantly until connected,results in the the surface of metal materials fall down,forms the debris.

The repeated extrusion of the materials,causes the metal materials of jaw plate is partially fracturing or turn up,the part together with the extruded materials falling down,forms the debris.

The materials do a short-range sliding relative to the jaw plate,cutting the jaw plate forms the debris.

The methods to reduce the jaw plate wear of jaw crusher in grinder mill:

Choose the jaw plate with hardness materials, high toughness,good comprehensive performance.The hardness materials,the material extruded with a shallow depth,and the materials have a small deformation,the cutting of the short-range sliding for the materials is small.High toughness,can increase the jaw plate's extrusion resistance,anti-break capability.

Transform the structure of jaw plate,reduce the materials and jaw plate's relatived sliding.
