采用CJXXM型行星磨对D97≤45μm的煅烧黑滑石进行了超细粉碎实验，研究了粒度区间对超细粉碎动力学模型形式的影响以及磨机转速、介质粒度和助磨剂对动力学模型中破碎函数的影响。结果表明，对于D97≤45μm的原料，其适用于一阶动力学方程形式的粒度比为15.67；煅烧黑滑石破碎函数最大时所对应的转速为1200 r/min；介质粒度与破碎函数呈幂函数关系，其关系式为k=0.26843 d-0.14478；助磨剂的使用有益于提高破碎速率函数，液态助磨剂三乙醇胺和乙醇的效果优于固态助磨剂六偏磷酸钠。

This paper studies the impact of size interval, mill rotation, media size and grinding aids on the form of kinetic and the breakage function by ultraifne grinding calcined black talc ofD97≤45μm in a CJXXM planetary mill. The results show that for the minerals ofD97≤45μm, the suitable particle size ratio which can be applied in the form of the ifrst order kinetics is 15.67. The rotational speed corresponding to maximum breakage function of calcined black talc is 1200r/min. The breakage rate is the power function of media size, the form of the power function isk=0.26843d-0.14478. Grinding aids can improve the breakage rate function, and the liquid grinding aids like triethanolamine and ethanol have a better effect than solid state grinding aid such as hexametaphosphate.
