The jaw plate of the jaw crusher is the core equipment of the crushed material, but it also affects the frequent damage and replacement of the seesaw due to the accumulation of materials and the nature of the material. However, if the purchase is not appropriate, not only will it not reach the previous crushing force, but it will also be damaged quickly. Therefore, how to choose a high-quality jaw crusher depends on the jaw plate quality of the jaw crusher. In addition to selecting the model and parameters, the following three points are also noted:

1. Manufacturing process of jaw plate

When selecting the jaw crusher, it is indispensable for the inspection of the manufacturing process. If there are small defects such as small cracks, shrinkage holes, and grain penetration in the interior or surface of the jaws sold by the manufacturer, we can buy such a seesaw. If you want to reject it, although it is less, it will reduce the performance of the seesaw and will even cause the jaw to break. Therefore, when purchasing, the slab must be made with a reasonable casting and heat treatment process. The establishment of a reasonable production process and strict quality inspection methods is a prerequisite for ensuring the performance of the raft.

2. The material of the jaw plate

Generally, the material of the jaw plate is high manganese steel, high chromium cast iron and low carbon alloy steel. Among them, high manganese steel is commonly used in high energy hydraulic jaw crusher, with high wear resistance, good toughness and good high temperature resistance. Its work hardening index is about 6 times higher than other materials, while high chromium cast iron has corrosion resistance. High, but the basic input of high manganese steel material, low carbon alloy steel material, is more suitable for other crushing equipment applications, currently rarely used in China. Through the comparison of these three materials, you should choose the application of high manganese steel material slab, which is not only specially made for crushing harder stone, but also cost-effective slab.

3. The structural design of the jaw plate

The design of the jaw crusher jaw plate directly affects the future crushing work. The jaws of different structures and geometries have different crushing properties. The thicker the fascia is, the harder it is forged, and the worse its wear resistance. Of course, the design of the seesaw is reasonable, not only can improve the service life, but also can fully break the material, especially the optimized design of the seesaw structure to improve the utilization rate. Therefore, when purchasing, the structure of the seesaw should be considered and analyzed.
