WHEN DO I NEED A COOLER FOR MY LRS?
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.

Liquid Resistance Starters GINO-AKA
Therefore, liquid resistance starters LRS are commonly used to start up WRIM motors. For liquid starters, the electrolyte solution of Na2CO3 or K2CO3 acts as a resistor, with the resistivity, in turn, depending on the soda concentration. By changing the distance between the upper and lower electrodes, the resistance is reduced smoothly.

Vapromatic type Liquid Resistance Starter
The passage of the initial rotor current causes immediate partial vaporization of the electrolyte and instantaneously adjusts resistance and starting torque to optimum values. During the run-up to speed, the thermal interchanges which occur progressively decrease the resistance. A limited contactor then short circuits the low residual resistance.
