What does Ball Mill Do?

The ball mill is mainly composed of cylindrical cylinder, hollow shaft, main bearing, feeding and discharging hollow shaft, motor, transmission gear and other parts. There are many lining plates in the cylinder, which can not only protect the cylinder, but also raise the steel ball to a certain height, so as to improve the grinding efficiency.

The difference between VFD and Soft Starter

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.
