VFDs provide accurate torque and speed control of mills. This reduces the stress on mechanical equipment such as gearboxes, especially during start-up and stopping, as same as during operation and maintenance. VFDs help to optimize the mill speed to match the material flow, thus minimizing the wear of the grinding mill. 2.Significant energy savings
