Structure and Microscopic Wear Analysis of Lining Material Based on EDEM

The microscopic influence of sliding distance and load on the wear of cone crusher liner is studied. The main factors that affect the hardness of the liner and the material are clearly put forward, and the hardness of the liner is verified according to the national standard to ensure the correctness of the lining and the ore material. Simulation experiments were carried out with EDEM. When the material was certain, the positive pressure and sliding distance between the ore and liner were changed, and the micro wear of the liner was quantitatively calculated by the number of bond keys of the lining plate. The results show that when the liner moves at the same distance, the pressure is greater and the lining plate is seriously worn. When the lining plate is subjected to the same pressure, the moving distance increases, and the lining plate is seriously worn. This method has some reference value for cavity design of new crusher and other material wear research.
