摘　　要：惯性圆锥破碎机是一种高效的细碎设备。为提高惯性圆锥破碎机的破碎性能,考虑矿石的非规则外形,构建了物料颗粒黏结模型,采用离散元软件(EDEM)对破碎机的破碎过程进行仿真研究,分析破碎区下半区域颗粒流动不均匀的原因。设计正交试验方案并进行正交仿真试验,运用MATLAB软件对仿真结果进行回归分析,建立以-5 mm矿产率为破碎性能评价指标与各试验因素的关系模型,利用遗传算法对试验结果进行优化。结果表明:当激振器转速为25.7 r/s、偏心力矩为1 340.6 N·mm、给料量为67.4 kg/s时,破碎机的破碎性能最佳。仿真研究结果可为惯性圆锥破碎机工艺参数的匹配优化提供参考。The inertia cone crusher is a kind of efficient fine crushing equipment.In order to improve the crushing performance of the inertia cone crusher,the irregular shape of ore is considered,the material particle bonding model is constructed.The simulation research on the crushing process of the crusher is carried out by using the discrete element software(EDEM),and the reason of the uneven particle flow in the lower part of the crushing area is analyzed.In addition,the orthogonal test scheme is designed,the simulation orthogonal test is carried out,the regression analysis on the simulation results is carried out by using MATLAB software,the relationship model with the-5 mm mineral yield as the crushing performance evaluation index and the test factors is established,the test result is optimized by using genetic algorithm.The results show that the crushing performance of the crusher is the best when the speed of the exciter is 25.7 r/s,the eccentric torque is 1 340.6 N·mm,and the feeding quantity is 67.4 kg/s.Therefore,a reference can be provided for the accouplement and optimization of technological parameters of inertia cone crusher.
