Abstract
Vertimill has been widely used abroad because of its high efficiency and energy saving in fine grind-ing, while it is introduced to China for the first time. In order to display the better performance of vertimill , the optimal working parameter is obtained when electric current is 45~52A , grinding density is (55 ±5) % and medium filling rate is 26 % by comparative study of dominant factors as current , grinding concentration and medium filling rate. The structure, working principles and ore grinding medium of the vertimill as well as the problems needing attention in the practical application of the vertimill are introduced. The economical and technical index of the vertimill and traditional ball mill are analyzed. Production practice in Yinshan plant shows that the operation cost can be saved with the steel consumption reduce d to 0.1 kg/t , energy saved by about 40 %, the content of the <45 μm in grinding product increased by 11 % , the recovery of copper and associated gold improved to 0.3%and 4%respectively .关键词
