Figure 3 shows the relationship between grinding fineness and specific grinding work for limestone, andesite, pumice, and tailings of ore processing in a laboratory stirred ball mill. The grinding fineness for limestone product can be determined by the specific grinding work and by an exponent with the Equation (4):
This means that during one rotation of the sun wheel, the grinding jar rotates twice in the opposite direction. This speed ratio is very common for Planetary Ball Mills in general. Planetary ball mills with higher energy input and a speed ratio of 1:-2.5 or even 1:-3 are mainly used for mechanochemical applications.

Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of …
Another type of ball mill is used to an increasing extent, where the mill is vibrated instead of being rotated, and the rate of passage of material is controlled by the slope of the mill. 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 ...
The vertical roller mill (VRM) which has gained wide acceptance in the cement industry and is used for grinding raw materials (mainly limestone), is a promising alternative. The VRM dries, grinds, and classifies ores and minerals within a single unit. ... A significant power saving of 39.2% was observed for the dry VRM compared to the wet …
