Common material types of jaw crusher jaw plate

As a kind of stone crushing equipment, the jaw crusher has heavy work and harsh working conditions. Even if with high quality jaw crusher, it is inevitable that wear occurs. Among them, the plate is the main wear-resistant part, which consumes a lot in the process of crushed stone, so the selection of plate material is particularly important. Today, this text will give you a detailed introduction of the commonly used material types of the plate, so as to help you better understand the jaw crusher, better purchase, operate and maintain the jaw crusher.

 

1.High manganese steel

High manganese steel is the traditional material of jaw crusher plate, which has good toughness and good deformation hardening ability. However, due to the unreasonable structure of jaw crusher at present, the opening angle between moving and fixed jaw plates is too large, which is easy to cause abrasive sliding, resulting in insufficient deformation hardening of high manganese steel, low surface hardness of jaw plate, large amount of short-range abrasive cutting and fast wear of jaw plate 。

 

2.Medium manganese steel

Because of the low initial hardness and yield strength of high manganese steel, its work hardening is not enough under the condition of non strong impact, and it is easy to flow and be cut. Therefore, in order to improve the service life of jaw crusher plate, technicians further developed and used medium manganese steel.

 

3.Composite of high chromium cast iron and high manganese steel

Although high chromium cast iron is an excellent wear-resistant material, it will directly break, deform and peel off when impacted or extruded by the material due to its poor toughness. Therefore, it is not a better choice to use high chromium cast iron to make the jaw plate. In recent years, high chromium cast iron has been cast in or bonded to the high manganese steel jaw plate to form a composite jaw plate. The high wear resistance of high chromium cast iron and the high toughness of high manganese steel have been brought into full play, and the service life of the jaw plate has been significantly improved.

 

 

4. Low alloy cast steel

Medium carbon low alloy cast steel is a kind of wear-resistant material which is widely used at present. Because of its high hardness and proper toughness, it can resist the cutting effect of materials and the fatigue peeling caused by repeated extrusion of materials, so it has good wear-resistant performance. At the same time, through the adjustment of composition and heat treatment process, the hardness and toughness of medium carbon low alloy cast steel can be changed in a large range to meet the requirements of different working conditions.

 

The above four kinds of materials are commonly used in the jaw crusher plate at present. Through analysis and comparison, it is not difficult to see that low alloy cast steel is used to make the jaw crusher plate, which is more high-yield, wear-resistant and has a longer service life.
