The Discrete Element Analysis Of Cone Crusher’s Crushing System

Cone crusher is a common material used in modern industry ore crushing and grinding equipment, metallurgy, construction, mining, chemical and other industries have appeared, its basic principle is to use equipment for extrusion and collision kinetic energy will be produced by granularity ore is broken down into smaller particles. In recent years, with "more crushing and less grinding", "broken ground" concept appeared, energy saving and efficiency becomes a cone crusher is an important indicator of design and production, become the trend of technology development of cone Crusher.As a producer of industrial country, daily consume huge amount of ore, coupled with the lack of related technology, making homemade quality of the cone crusher and the performance indicators relative to foreign products have a certain gap, advanced domestic sources of cone crusher is mainly for import. Based on Sweden Sandvik company for the study of H8800-type cone crusher, distinct element analysis of its crushing system, its work force of State agencies.Firstly, cone broken machine of broken system for has research, find the on whole broken system work State effects larger of parameter, as to material mouth and row material mouth size, and angle, and moving cone speed, and into moving angle,, then using Solid Works software on H8800 type cone broken machine of broken system for three dimensional built die, which including core axis, and moving Cone, and moving cone lining Board and set cone lining Board.Next according to discrete method and using EDEM software on H8800 type cone broken machine of broken system in work State Xia of by force situation for discrete Yuan analysis, first will has in Solid Works software in the established good of broken system three dimensional model import EDEM software in the, established material particles model, set simulation parameter and for related operation, will moving cone speed, and into moving angle and material particles set for variable, respectively on its in different moving cone speed, and Under different feeding granularity of cone Crusher system for simulating the working conditions, the resulting cone linings, conical ore liners as well as material forces, and find out the different parameters on differential impact of crushing system of working state. Eventually came to the conclusion that: Cone speed increase on the cone Crusher system can improve the efficiency of, but will hasten the movable cone liner and wear of cone lining; increasing precession Crusher capacity can be improved, but the cone Crusher performance will decline.In the paper can be designed for the production of cone Crusher provides some data on the reference, and lays the Foundation for more in-depth study.
