The liner of the cone crusher is easily worn out because of the strong impact. This will lead to uneven product size, reduced production efficiency and increased energy consumption, so the replacement of crusher linings is very important. Material of cone crusher liner at present, the material used in cone crusher liner is high manganese steel. According to the investigation of the service life of the cone liner of some cone crushers installed in China, the service life of the cone liners used in various factories and mines is very different, which is caused by the difference of ore properties and crusher loads.
After the liner is worn, the excitation force and feeding amount of the vibrating feeder cannot be adjusted in time, which causes the feeding space of the cone crusher to be filled with too much material, and the relative movement between the movable cone, the top bearing body and the ore produces friction.
In the early stage of use of the liner, the shaft and sleeve above the movable cone lock cap will be worn; in the later period of use of the liner, as the distance between the lock cap and the top bearing becomes smaller, it will also cause the lock cap, top bearing body, Shaft sleeves and oil seals are worn out. However, the wear of the lock cap and the top bearing body is difficult to determine quantitatively whether to replace the liner. The replacement is early, causing unnecessary economic losses, and the replacement is late, the liner is worn through, and the moving and fixed cones are damaged. If you are not aware of the wear of the top bearing body, and the top bearing seal cannot be fixed, if it cannot be handled or handled improperly, the upper frame and top bearing of the cone crusher must be replaced, causing major economic losses.
