Optimization Design of the vertical roller mill Cavity

0 voti

The vertical roller mills are the main crushers for crushing the bulk materials,which are widely used in the metallurgical and mining industries. However, the irrational cavity structure design leads to low efficiency and high energy consumption, which can not meet the need of modern industrial production. Henan Mining Machinery uses multi-objective optimization for research and analysis of the vertical roller mill sale cavity type structure and has got the cavity type curve and the particle size distribution curve after optimization. The optimized cavity is closer to the ideal cavity curve which can provide specific reference data for the actual production of the vertical roller mill and can provide good example for further research to improve the performance of vertical roller mill.

The vertical roller mill is widely used in different sectors of the national economy to meet the needs different crushing operations. Since the design of the vertical roller mill is age-old with conservative design ideas, the efficiency is low with high energy consumption, which can not meet the needs of modern industrial production. Therefore, the performance of the vertical roller mill needs to be optimized to improve the efficiency and improve the quality of the crushed product.

The moving cone, fixed cone and angle of the vertical roller mill form the geometric cavity of the vertical roller mill. In the crushing operation, the moving cone periodically closes or it is aloof from the fixed cone. When the moving cone closes the fixed cone, the materials between the two cones will be crushed by huge squeeze pressure. The materials away from the cone surface will fall down because of their own gravity. The movement of the materials in the crushing cavity is very complex. The analysis of the movement of materials is to analyze the motion of the particles.

When the swing speed of the moving cone is lower, the particles first do freely falling body movement. With the increase of swing speed of the moving cone, the crushing number of the particles gradually increases. After crushing, the grain size of the product will be getting smaller and smaller.
