There is not much tolerance on the start-up torque of a Ball mill, both too high and too low starting leads to problems. With a normal LRS, we would only recommend starting a Ball mill between 130% and 140%. An 8MW ball mill will typically increase the water temperature by 3°C and the torque with roughly 6.6% on each start-up.

Typically LRS in these situations are used to start only, and when motor has reached a certain speed, the rotor is short circuited and it acts like an squirrel cage motor. Some manufacturers offer brush lifting systems, which will raise the slip ring brushes when motor reaches nominal speed and increase the lifetime of the brushes.
