Obrolan LangsungThe ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
Obrolan LangsungSTEEL. Steel Shot: There are many sources for steel shot but all are not equal since much of the steel shot is used for shot peening. Make sure that the shot is designed as a grinding media or it could tear up the mill. Steel shot is one of the least expensive grinding medias with the benefit of high density and the availability of a wide range of sizes for small media.
