摘要:
首先通过软件CATIA建立立轴冲击式破碎机简化模型,然后基于离散元软件EDEM黏结接触模型对立轴冲击式破碎机进行破碎仿真,即分析瞬态的破碎过程又探究不同转子直径、转子转速、入料粒径和入料量对颗粒甩出速度、破碎率和转子功率的影响规律,并且分析颗粒甩出速度与破碎率之间的关系,最后将实际转子功率与仿真转子功率进行对比,验证仿真结果的可靠性。结果表明,破碎率随着转子转速和转子直径的增大而提高、随着入料量的增加而降低、随着入料粒径的增大先提高后降低;转子功率随着转子转速、转子直径和入料量的增大而大幅增大。综合考虑破碎率与转子功率,本文仿真范围内转子转速1600r/min、转子直径1100mm、入料粒径30mm、入料量160t/h为最优组合参数。
Abstract:
Firstly, the vertical shaft impact crusher simplified model was established by using the software CATIA, then the crushing process of the vertical shaft impact crusher was simulated ba<x>sed on the discrete element software EDEM bonding contact model. In this paper, the transient crushing process of the vertical shaft impact crusher was analyzed and the influence laws of different rotor diameters, rotor speeds, feed particle sizes and feed rate s on the velocity of particle ejection, crushing rate and rotor power were investigated. In addition, the relationship between velocity of particle ejection and crushing rate was analyzed. Finally, the reliability of the simulation results was verified by comparing the actual power and simulation power of the rotor. The results shown that with the rotor speed and rotor diameter increase, the crushing rate will increase while with the feed rate increases, the crushing rate will decrease with the feed particle size increases , the crushing rate will increase at first and then decrease. In addition, with the rotor speed, rotor diameter and feed rate increase, the rotor power will increase greatly. Considering the crushing rate and rotor power comprehensively, when rotor speed is 1600r/min, rotor diameter is 1100mm, feed particle size is 30mm and feed rate is 160t/h, this set of parameters is optimal in this paper
