5 有关问题的评述5 1 关于自磨与常规磨矿与常规碎磨流程比较 ,自磨的主要优点是 :能接受较大的给矿粒度 (最大粒度一般为 3 50～ 2 0 0ｍｍ ) ,因此可以取代中、细破碎及粗磨作业 ,减少生产环节和粉尘污染 (对湿式自磨 ) ,简化车间组成和占地面积 ;具有一定的选择性碎磨作用
5 COMMENTS ON THE PROBLEMS 5 1 The main advantages of self-abrasion compared to conventional grinding and conventional grinding are the ability to accept larger feed particle sizes (maximum particle size typically 3 50 to 2 0 0 mm) and therefore Can replace medium and fine crushing and rough grinding operations, reduce production processes and dust pollution (wet self-grinding), to simplify the composition and floor space; have a certain degree of selective grinding
