Ball Mill Grinding Capacity Calculator Ball Mill Motor/Power Sizing Calculation Ball Mill Design/Sizing Calculator The power required to grind a material from a given feed size to a given product size can be estimated by using the following equation: where: W = power consumption expressed in kWh/short to (HPhr/short ton = kWh/short ton) Wi ...

The starting torque characteristic of this type of ball mill is not linear. Figure 2 shows the graph of mill speed versus torque requirement: Figure 2 The graph clearly shows that the torque requirement exceeds 120% at 80% speed. This is why the starting torque of the drive motor should be at least 130% of full load torque.
