2014-1-2 for a recent ball mill is shown in Figure 2. Mill suppliers define the starting torque at an angular displacement of the charge. The cascading point of this mill is at angle of 60°. This implies that a motor connected through a 60:1 reduction be capable of transferring 120% of its rated full load torque when it has turned through 10 revolutions.

2018-4-15 Starting of the mill is possible by either using two of the 1250kVA sets or one 1250kVA and the 500kVA set. No theoretical analysis had been performed on the system, due to being an existing plant. Commissioning on site involved testing the LRS for the correct resistance to ensure the mill motor would develop ample torque to accelerate the mill.

The starting torque is extremely high. For example, for a 110 kW motor with a ratio starting torque / nominal torque of 2.4, this torque is applied by the motor shaft to the driven machine which can make either an early ageing of the mechanical coupling (transmission shaft or transmission belt) or even the break of the driven machine.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
