Abstract

Abstract:

In order to improve the efficiency of material crushing and solve large material jamming in open-pit mine crushing stations, the bulk material model and the mathematical model of material particle size were established. Firstly, the factors affecting the crushing force of the material were analyzed, and the mathematical models of crushing force under the action of different factors were established. Then, the CR610/14-35 double-toothed roller crusher was taken as an example, and the force of different materials under different center distances and tooth heights of the toothed roller was numerically simulated. The results show that the particle size, the center distance, and the tooth height of the toothed roller are the main factors affecting the passing capacity of large materials in the crushing station, and the tangential force of the material decreases with the increase in the center distance of the toothed roller and increases with the increase in the tooth height of the toothed roller.

Key words: double-toothed roller crusher, material particle size, tangential force, center distance, tooth height
