针对目前球磨机粉磨超细矿渣的缺点 ,本文探讨使用PDM型立磨来生产超细矿渣。研究表明 ,经过改造的立磨———PDM型立磨生产的超细矿渣的粒度、活性系数等性能均与球磨机粉磨的矿渣相当 ,但立磨的电耗、磨损远小于球磨 In view of the shortcomings of the current mill grinding superfine slag, this paper discusses the use of PDM vertical mill to produce superfine slag. The research shows that the modified vertical mill --- the particle size and the activity coefficient of the ultrafine slag produced by the PDM vertical mill are similar to those of the ball mill, but the power consumption and wear of vertical mill are far less than that of the ball mill
