摘要： 为了减小研磨后海泡石矿粉粒径及其分布宽度，基于层压破碎理论，研制了一款螺旋搅拌磨机。利用工程离散元法（engineering discrete element method，EDEM）对海泡石研磨进行仿真，研究介质球在研磨腔的运动规律，以介质球的速度梯度、旋转动能和搅拌磨机的磨损量为评价指标来获得最优工艺参数。采用自行研制的螺旋搅拌磨机进行海泡石研磨实验，并对研磨后的海泡石矿粉进行粒径检测。仿真和实验结果表明：当磨机转速和介质球直径较小时，可以获得粒径及其分布宽度较小的海泡石矿粉，同时磨机的磨损量较小。研究结果可为海泡石研磨设备的优化和最优工艺参数的确定提供参考。
Abstract: In order to reduce the particle size and distribution width of sepiolite ore powder after grinding, a spiral stirring mill was developed based on laminated crushing theory. The sepiolite grinding was simulated by EDEM （engineering discrete element method) to study the motion law of the dielectric sphere in grinding cavity. The optimal process parameters were obtained by taking the velocity gradient, rotational kinetic energy of dielectric sphere and wear amount of stirring mill as evaluation indexes. The self-developed spiral stirring mill was used to carry out sepiolite grinding experiment, and the particle size of the sepiolite ore powder after grinding was detected. The simulation and experimental results showed that sepiolite ore powder with relatively small particle size and distribution width could be obtained when the rotating speed of mill and diameter of dielectric sphere were relatively small, and the wear amount of the mill was relatively small. The research result can provide reference for the optimization of sepiolite grinding equipment and the determination of optimal process parameters.
