Abstract

“Rock bed” mechanism and its formation were discussed in this article. Inspired by the bionic wear-resistant structure, the shape and parameters of an impact crusher chamber are optimized. Taking both crusher strength and crushing effect into consideration and using discrete element method, the parameters of the impact crusher chamber were properly optimized. By adjusting the major parameters and structures of the factors (rotor speed, angles of the first and second impact plates, shape of impact plate and blow bar material) influencing crushing effect, the orthogonal test with four three-level factors was conducted to find an optimal combination with the best crushing effect so as to optimize the impact crusher.

摘要

本文讨论了“岩床”机制及其形成。受仿生耐磨结构的启发，对反击式破碎机腔的形状和参数进行了优化。综合考虑破碎机强度和破碎效果，采用离散元法，对反击式破碎机腔室参数进行了适当优化。通过调整影响破碎效果的因素（转子转速、一、二反击板角度、反击板形状和板锤材料）的主要参数和结构，进行四个三水平因素的正交试验，找到一个最佳破碎效果的最佳组合，从而优化反击式破碎机。
