mill. As such, primary ball mills should be designed with the rod mill work index, and singlestage ball mills should be with both the rod mill and ball mill indices. This is because it is common to observe a difference (sometimes significant) between the rod mill and ball mill index values for a given ore type (McKen, Verret, Williams, 2006). On
In the case of the stirred mill using a single ball size, the index k varies from 1 to 3, corresponding to ballball collisions, ballscrew collisions and ballliner collisions. b 11 ( eE ) is the body breakage distribution function in density form, which also depends on the magnitude of each stressing energy [ 34 ] and κ 1 is the rate of mass ...
The batch ball mill is a ball milling machine that discharges the material at one time according to the nature of the material.
