Jaw Plate

The jaw plate, also known as the tooth plate or pressure plate, is the main working part of the jaw crusher. The material is crushed by the extrusion and splitting action between the movable jaw plate and the fixed jaw plate. Wear is mainly caused by sliding friction and repeated extrusion of the material, which manifests as surface cutting, crack expansion or material shedding. In order to increase the service life, it is critical to choose a high-performance jaw plate.

Jaw crusher is a common coarse crushing equipment in sand and gravel production lines. It's core components are the two jaws, fixed jaw and movable jaw. Chengdu Zhixin Refractory Technology is manufacturer of crusher wear parts, including jaw plates, liners, compound steel plates. 

The jaw plate of jaw crusher is divided into fixed jaw plate and movable jaw plate, generally both of them are high-manganese steel castings. When working, the movable jaw is attached to the movable jaw plate to make a compound swing motion, forming an angle with the fixed jaw plate to squeeze the stone. Therefore, the jaw plate of jaw crusher is easy to wear and needs to be replaced within a certain period of time. In order to extend its service life, its shape is generally designed to be symmetrical up and down, that is, it can be turned around when one end is worn. The movable jaw plate and the fixed jaw plate are the main contact surfaces when crushing stones. The movable jaw plate is installed on the movable jaw to protect the movable jaw.

The jaw plate is one of the core components of the jaw crusher, including the movable jaw plate and the fixed jaw plate. When working, the jaw peaks of the movable jaw and the fixed jaw should face the jaw valleys. In this way, in addition to the squeezing effect on the material, there is also a bending effect during crushing, making it easier to crush the material. 
The material of the jaw plate is usually manganese steel containing more than 13% manganese, and ZGMn13 and ZGMn18 are commonly used. Our high-performance jaw plates are added with specially developed alloys to further improve the wear resistance of the jaw plates and extend their service life.
