liquid resistor starter for mill

 · Wound-rotor motors use resistance in the rotor circuit to control torque and speed. That resistance can be large, high-wattage physical resistor grids switched with contactors, or it can be a liquid rheostat. The resistor grid allows for “stepped”...

wound motor with liquid resistor starter for mill. Milling Energy intensive and high maintenance. system, couple the motor to the mill. Another possibility is to use a motor that can develop sufficient torque such as the wound rotor induction motor with rotor resistor starter.

that the mill be started using a procedure that minimises the probability of a locked charge start. This procedure is detailed later in the article. Hard start of mill motor, throwing ball charge Most mills are designed with a soft starter arrangement; a typical mill starter system could include a Liquid Resistor Soft Starter (LRS)

Liquid Resistance provide high starting resistance to rotor circuit, cutting the resistance sleeplessly synchronizing with Motor Acceleration to very low or negligible value near Full Load speed. This gives a high Starting Torque and very smooth start. The above figure shows the comparisons of Grid Resistance Start and Liquid Resistance Start.
