摘　　要：通过条件试验,系统地研究了超细搅拌磨机中磨矿介质及其尺寸、磨机转速、球料比、分散剂及其用量等主要参数对重钙研磨效果的影响规律,并分析了原因,为工业生产中确定适宜的参数提供了理论依据。同时,应用超细搅拌磨机通过两段研磨试验制备出了-2μm粒级含量为95.52%、最大粒径为3.08μm、固含量为75.3%、粘度为290 mPa.s、白度为93.52%的高档造纸涂布级重钙浆料,对工业化大生产具有重要的指导意义。The influence laws of the main parameters of uhrafine stirring mill, such as grinding media and their size, agitation speed, dispersants and their dosage, and the weight ratio of grinding ball to feeding material, on the grinding effect of GCC were investigated and the relevant causations were analyzed by condition experiments, and the results provide a theoretic basis to determine properly the processing parameters for industrial production. After a two stages of grinding, a coating GCC pulp with the content of - 2μm fraction of 95.52%, the maximal size of 3.08μm, a solid content of 75.3%, a viscosity of 290 mPa·s and a whiteness of 93.52% can be prepared by uhrafine stirring mill.
