Jaw crusher is a kind of crusher which can complete material crushing operation by simulating the movement of two jaws of animals. It is used in mining, building materials, infrastructure and other departments. In the design, the tooth peak of the broken plate of the moving jaw and the fixed jaw is opposite to the tooth Valley, and the material is squeezed and bent when it is broken, which makes the material easier to be broken. In order to adapt to different occasions and materials, the choice of jaw plate material of jaw crusher is also considered by manufacturers
1. White cast iron
The white cast iron has the advantages of high hardness, good wear resistance, easy source and low price, but it is brittle, easy to break and short service life.
2. High manganese steel
High manganese steel is the traditional material of jaw plate of jaw crusher, which has good toughness, deformation and hardening ability, long service life and low cost. However, the price is expensive and the hardness is not high. At present, the unreasonable structure makes abrasive wear the jaw plate seriously.
3.Medium manganese steel
Compared with high manganese steel, the wear resistance is improved and the service life is longer after the manganese content is reduced, which is suitable for medium and small jaw crusher.
4. Low alloy cast steel
In conclusion, the jaw plate material of jaw crusher must be able to withstand plastic wear and cutting wear, which requires the material to have high hardness and certain toughness. In practice, we must fully understand the working conditions, material hardness, wear mechanism and technical economy before making a choice.
