Tooth plate of jaw crusher, also called lining board, is a component which contacts ores directly. Although it has a simple structure, it has influence on productivity, energy consumption ratio, products granularity and crushing force, especially the last three influences will give big impact force to tooth plate.

We know that the mining equipment has a certain service life, and jaw crusher is not an exception. After a long time of application, its tooth plate, bearing, jaw plate and other components will have abrasion, so they all need replacement. We should know its reasons and solutions of abrasion, so here Hongxing Machinery suggests some methods to you:

First of all, we should improve its abrasion resistance from its raw materials, mainly hardness and toughness. If the raw material has a high hardness, it will have a small deformation faced with materials to be processed. The raw material with high toughness will have strong ability to resist fracture, eliminate the brittle fracture during squeezing and impact process and improve its fatigue and deformation resistance ability.

Second, the jaw crusher has different specifications. Its differences like feeding granularity and sharpness will provide different squeezing and impact force. The large and medium machine has big squeezing force and large production. Apart from the materials' pressure and sliding cutting resistance, we should also consider its impact and bending stress force. So the large tooth plate should adopt materials with high toughness and good comprehensive performance.

At last, the raw materials of tooth plate should adopt hard materials to resist squeezing force. Customers should understand the abrasion reason of jaw crusher's components and improve the tooth plate accordingly to reduce the relative sliding between materials and tooth plate, which is not only beneficial for productivity improvement, but also for service life extension.
