围绕着降低球磨机的能量及介质消耗,国外对球磨机衬板形状进行了大量研究工作,取得了一些进展。其中当首推角形螺旋衬板(简称ASL)系统的研制和采用。角形螺旋衬板系统以其明显的经济效果引起了各国的重视,发展较为迅速。角形螺旋衬板系统最初是由奥地利瓦格纳—比罗公司(Waagner—BiroAG)研制的。近十年来已在美国,智利和菲律宾等国大型选矿厂的近50台球磨机上采用,效果甚佳。与常规衬板相比较,一般可降低能量和介质消耗量10～20％左右,处理能力略有提高,磨矿产品粒度分布特性保持不
Around the ball mill to reduce energy and media consumption, the shape of the ball mill abroad a lot of research work and made some progress. Which when the most important angle spiral lining (ASL) system development and adoption. Angular spiral lining system has drawn the attention of all countries with its obvious economic effect, and has developed rapidly. Angular spiral lining system was first developed by Waagner-BiroAG in Austria. Nearly 50 ball mills that have been used in large-scale beneficiation plants in the United States, Chile and the Philippines over the past decade have achieved very good results. Compared with the conventional liner, generally reduce energy and media consumption of about 10 to 20%, a slight increase in processing capacity, grinding product particle size distribution characteristics remain unchanged
