【摘要】：球磨作為一種介質運動式粉碎工藝,廣泛應用于冶金選礦、陶瓷、化工、建材等大型工業(yè)部門,在眾多成本中球磨介質磨耗占據較大比例。本文采用重量法通過調整球磨參數得出球磨介質的磨耗規(guī)律。結果表明:隨著球磨時間延長,介質質量不斷減小;在一定范圍內,隨著球磨轉速增加,球磨介質磨損加越快;在一定范圍內,隨著料球比增加,球磨介質磨損減慢;隨著大小球比值增加,球磨介質磨損總量在減小,但磨損速度基本不變。當球料比為1∶0.3,大小球質量比為1∶0.5,轉速為110 r/min,工業(yè)球磨石英砂粉體球磨介質的磨損預測:石英砂原礦球磨到粒徑為11.25μm,球磨介質磨耗與石英砂粉體產量的磨耗約為3.17 kg/t。
[Abstract]:As a kind of medium moving grinding process, ball milling is widely used in metallurgical mineral processing, ceramics, chemical industry, building materials and other large industrial departments. Among many costs, ball milling medium wear accounts for a large proportion. In this paper, the wear law of ball milling medium is obtained by adjusting the parameters of ball milling by gravimetric method. The results show that the medium quality decreases with the prolongation of ball milling time, the wear of ball milling medium increases faster with the increase of ball milling speed in a certain range, and slows down with the increase of ball ratio in a certain range. With the increase of small ball ratio, the total wear amount of ball milling medium decreases, but the wear speed is basically unchanged. When the ratio of ball to material is 1 鈮，
