Thus, most of the grinding aid studies focus on this mill type, which makes it difficult to compare the grinding aid performance for different grinding mechanisms. Also, tumbling ball mills are usually operated within a narrow range of process parameters, since the choice of parameters like mill speed and ball size is strictly limited.

For ball mills, it is more efficient to reduce the size of large particles prior to the mill, using physical means such as a hammer crusher, pregrinder, or a roll press. Fine clinker is less of an issue in a ball mill, since the material simply passes through to the second chamber for fine grinding, although this can reduce the impact of the ...
