Addition of pebbles to a ball-mill to improve grinding ...

2020-2-22When the proportion of pebbles in the mill charge was low up to 30, the larger pebbles wore away significantly faster than expected, based on a constant surface wear rate. This could be due to size segregation in the mill. CITATION. Nkwanyana S and Loveday B. Addition of pebbles to a ball-mill to improve grinding efficiency.

A study of comminution in a vertical stirred ball mill.

The energy input per ton of grinding media in the stirred ball mill could be 10 times higher than for the tumbling ball mill. Although during coarse grinds the media wear was higher in the stirred ball mill than in the tumbling mill, it became less so as grinding proceeded and for a product median size of 4.8 microns it
