Abstract
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.
Highlights
When the cone crusher breaks the ore, the movable cone liner is worn by the squeezing action of the ore, so the movable cone liner needs to be replaced regularly
The effect of different sliding distance and load on the wear of the movable cone liner under the dry friction condition is studied by using the discrete element method to study the effect of the composite material and the crushing cavity type Provide reference
In order to study the wear of the movable cone liner, it is necessary to construct the dynamic cone liner material and the ore material
Summary
When the cone crusher breaks the ore, the movable cone liner is worn by the squeezing action of the ore, so the movable cone liner needs to be replaced regularly. The research on the wear of the movable cone liner is very important. It has been found that the wear of the movable cone liner depends on the wear properties of the liner material and, on the other hand, the mechanical action, such as the sliding distance between the movable cone liner, the ore and, the load of the movable cone liner [1]. The effect of different sliding distance and load on the wear of the movable cone liner under the dry friction condition is studied by using the discrete element method to study the effect of the composite material and the crushing cavity type Provide reference
