The liquid resistance starter, also known as liquid rheostat (LRH), is programmed to drive the electrode downward as the motor accelerates to reduce the resistance approximately proportional to the reduction of secondary voltage. This will enable the motor to maintain the rotor current relatively constant during the acceleration of the motor.

A very basic overview, but the advantage of wound rotor slip ring motor is that, through a LRS u can vary the resistance of the rotor. The advantages are 1. able to manipulate the torque speed curve, allowing u start with a much higher torque. Wound motors are suitable for application with heavy starting duties such as ball/sag mills, crushers etc.

Reason #2：The supplement of steel balls is insufficient. Due to the longterm operation of ball mill, the steel balls will wear violently, the diameter will be reduced, and the impact force will be correspondingly weakened. When the steel balls in the ball mill are not replenished in time, the processing capacity of the ball mill will be reduced.

This is the ratio of the maximum resistance of the LRS to the minimum resistance before the short is placed in position. The short is placed in position with a shorting contractor. A good turndown ratio will limit the starting torque of the motor to an acceptable value. A good turndown ratio for a 5mW LRS is a 100 or more.

There is a large gap between the tip speed and power intensity of the lowspeed vertical mills and the highspeed horizontal mills. The VXP mill bridges the gap between highspeed and lowspeed mills. The VXPmills are designed for fine and ultra fine grinding applications. In practice, the mill performs best when the feed has a normal distribution.
