1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of ...

Fig. 1 shows typical charge shapes predicted for our 'standard' 5 m ball mill and charge (described above) filled to 40% (by volume) for four rotation rates that span the typical range of operational speeds. For such a charge with a realistic size range, the free surface of the charge is well defined at low and intermediate rotation rates. For N=60%, material moves with the mill rotation ...
