2022 2 1 The ball mill is used for the grinding of a wide range of materials including coal pigments and felspar for pottery and it copes with feed up to about 50 mm in size. The efficiency of grinding increases with the hold up in the mill until the voids between the balls are filled. Further increase in the quantity then lowers the efficiency.

Get PriceBall mill operation is often regarded as something of a mystery for several reasons. Ball milling is not an artit's just physics. The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables are non linear or have paradoxical effects on the end results.
