When working in the cone crushing station, if the stone powder content and humidity of the material are relatively high, it will easily adhere to the crushing wall and the rolling mortar wall during crushing. Over time, it will not only reduce the production efficiency, but also affect the crushing wall and the rolling Mortar wall corrodes and reduces its service life.

1. Content of crushed stone powder and humidity of crushed material
When working in the cone crushing station, if the stone powder content and humidity of the material are relatively high, it will easily adhere to the crushing wall and the rolling mortar wall during crushing. Over time, it will not only reduce the production efficiency, but also affect the crushing wall and the rolling Mortar wall corrodes and reduces its service life. For materials with relatively high content of stone powder, before crushing, it should be passed through a sieve, so that excessive fine powder can be avoided when crushing; for materials with high humidity, certain measures should be taken before crushing Reduce the moisture content, such as natural drying or mechanical drying.
2. Hardness and particle size of crushed material
According to the different hardness of the crushing material of the cone crushing station, the degree of wear of the crushing wall and the rolling wall is also different. The higher the hardness of the material, the more difficult it is to crush, the greater the impact load on the crushing wall and the rolling mortar wall in production, and the service life will be shortened accordingly; when the hardness of the material is the same, the larger the particle size of the material entering the crushing cavity, The more serious the wear of the lining board, the shorter the service life.

High manganese steel has high tensile strength, plasticity and toughness and weak magnetism. Under the condition of high speed and heavy load, the working face will form a work hardening layer, which has good wear resistance. At the same time, it also has austenite. Even if the parts are worn to a very thin thickness, it can still withstand a large impact load without cracking, and will not cause secondary damage to the equipment itself.
The broken wall and rolling mortar wall of the cone on the market are generally made of high manganese steel.
Add lubricating oil during installation: when installing the crushing wall of the cone crusher, it is necessary to pour zinc alloy into the crushing wall. Before pouring zinc alloy, the crushing wall or the inner surface of the lining plate can be coated with a thin layer of lubricating oil, which can not only avoid moisture, but also increase the durability of the crushing wall and prolong the action time.
Broken wall, pricked wall is a very strong mechanical equipment, which can be carried out very well is to check its firmness before use, this will promote the efficiency of use more quickly.
