jc soft start advantages and disadvantages of ball mill

Besides of the motor soft starting, VFD also can control the motor speed, to save energy. Cost: VFD's cost may be as high as triple as the soft starter. If the motor works at full load all the time (means no need to vary the speed), then soft starter is your selection. In other case, say the ball mill works at 80% load, then choose the VFD, the ...

Oct 05, 2015· The disadvantage of the soft starter technology compared to the frequency converter is that it is unable to control the speed and is unsuitable for applications requiring speed control. When starting loads with high inertial torque, for example in ball mills, it is easily applicable and has to be selected at a higher power level.

The difference between VFD and Soft Starter

These soft starters can restrict induction AC motor starting voltage effectively during motor start-up period, which can be widely used in fans & pumps, compressors and other heavy load equipments. Applications: Pumps, Fans, Ball mill, Compressor, Belt conveyor etc.
