Investigating the effect on power draw and grinding

2021/1/1The design and operating parameters of a stirred media mill have an effect on the efficiency of the grinding process occurring in the mill. There are many factors that can influence efficiency. Some of the main factors are the physical mill design, the choice of grinding media size and density, the speed of the stirrer, and the slurry density ( Jankovic, 2003 ). Get price

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 was the same.
