    The advantages of improved ball mill. The VFD start is the soft start, which has avoided the start-up impulse current in the ing frequency. Meanwhile, it will protect the equipment. It can operate as the set multi-stage PLC which is set automatically. The operation mode of multi-stage speed can reduce the input current in the status of lower than the ing frequency. Under the conditions
