In the first survey the ball mill was underperforming due to the low density in the mill, which was rectified in the second survey. The ball mill was grinding to a P 80 of 50 to 70 m, therefore the traditional marker size (75 m) was not applicable, and this can be seen by the increase in SSE for coarser sizes as the marker size approached P ...

The grinding efficiency of the system is also enhanced because qualified fine powers from the roller press don’t need to be ground again by the ball mill. However, due to the fact that part of the finished cement produced by this system has not been ground by the ball mill, its particle uniformity and working performance may be slightly worse ...

Over the years, it has been determined that Efficiency Factors (EF1 to EF9) should be applied to Equation 1 to drive the corrected power requirement (Rowland, 1982). The equation for Third Theory of Comminution Bond’s was originally developed for use with conventional crushing and grinding circuits (crusher-rod-ball mill or crusher-ball mill).
