III. The advantages of improved ball mill. The VFD start is the soft start, which has avoided the start-up impulse current in the working frequency. Meanwhile, it will protect the equipment. It can operate as the set multi-stage PLC which is set automatically.
When using a synchronous motor we recommend having 200% starting torque, 120% to 130% pull-in torque, and 225% pull-out torque. These assume no greater than a 10% voltage drop at the motor terminals. V-BELT Ball Mill DRIVE V-belt or poly-V drives are generally used on grinding mills consuming 350 HP or less.
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) or Variable Frequency Drive (VFD), or it could be a clutch. Regardless of the system used, it is important to use correct start settings so that the start ...
of ball mill, and maintains the motor with steady operation state when the equipment is running at variable frequency, ensuring the motor has constant power characteristics. 2. The ball mill frequency control and speed regulation system makes ball mill running reliably at low speed, ensuring the normal process control requirements.

SD300Q series special AC drive for ball mill is a high-performance energy-saving control product, it mainly used for control and adjust the of the speed and torque of the three-phase AC asynchronous motor, which is a new generation technology upgrade product in SINOVO.
Ball mills on the other hand, as far as process requirements are concerned, did not require variable speed. However, frequency converter based drive systems provide benefits that improve the ball mill operation. FIXED SPEED CONFIGURATIONS The key issue to operate a mill in a fix speed mode is the starting.

The difference with Soft Starter vs Variable Frequency Drive (VFD) is the method of starting employed. A soft starter reduces voltage, not Hertz, and as such the starting torque at 2-3 Hz is next to nothing. The soft starter is essentially robbing the motor of voltage at all points between 0 and 59 Hz, peak (Line) voltage met at 60 Hz.
