球磨机的衬板具有双重任务:它保护筒体避免磨損,也是把能量传給磨矿介质的最后一个传递环节。衬板本身也要磨損。按塔加尔特的資料,包括废料在內,筒体衬板和端盖衬板每磨碎一吨物料的平均磨損量为0.1公斤。在最近15年来,抗磨材料的质量大为改进,尤其是使用商品名称为“硬鎳”(Ni-hard)的耐磨材料以来,減少了衬板的磨損。材料不断改善衬板的形状并沒有改变。当然,目前有很多类型的衬板形式;过去用合金
Ball mill liner has a dual mission: It protects the cylinder from wear and tear and is the last transfer of energy to the grinding media. Liner itself also wear. According to Tagart, including scrap, the average wear volume per barrel of crushed material for cylinder liners and end liners is 0.1 kg. In the last 15 years, the quality of wear-resistant materials has greatly improved, especially with the use of wear-resistant materials under the trade designation “Ni-hard”, which reduces wear on the liner. The material continues to improve the shape of the liner and has not changed. Of course, there are many types of liner forms; past used alloys
