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.

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.

Operating principle of Vapromatic type LRS This is based on the difference in resistivity between a liquid electrolyte and its vapour, contained in an electrode chamber. The passage of the initial rotor current causes immediate partial vaporization of the electrolyte and instantaneously adjusts resistance and starting torque to optimum values.
