小小磨球在矿山生产中充当着磨矿介质的重要角色，寿王坟铜矿选矿厂采用低铬合金磨球取代贝氏体磨球做磨矿介质，收到了显著的经济效益。该厂过去一直使用贝氏体磨球做磨矿介质，由于其破碎率高，影响了磨矿效率，导致磨矿台效低，磨矿细度低，而且常因碎球堵塞排矿槽和返... Small grinding ball plays an important role in grinding media in mine production. Shouwangfen Copper Concentrator adopts low chromium alloy grinding ball instead of bainite grinding ball to make grinding media, and has received significant economic benefits. In the past, the mill used bainitic grinding balls to make grinding media. Because of its high crushing rate, it affected the grinding efficiency, resulting in low grinding efficiency and low grinding fineness. return...
