Variable Frequency Drive Inverter Universal for Ball Mills for Fans
This system starts up the ball mill progressively until it reaches its rated speed, at which point the drive synchronizes the ball mill to the grid frequency to switch to fixed speed operation. After that, it is connected to the SAG mill which works at a variable speed while remaining under control by the drive at all times.

Conventional mining process circuits use both Semi-Autogenous Grinding (SAG) and Ball mills. It is very common that the SAG mills are operated with adjustable frequency drives (AFDs) and the Ball mills are operated at fixed speed [1]. Recently, however, adjustability of Ball mill speed has been given more consideration. Also, to maximize throughput, the Ball mills are sized to be operated at

The SD Dry Grinding Attritors can be operated in both continuous and batch processing applications. In the continuous operation, the material is fed into the vessel at the top. It then migrates through the agitating media bed where it is processed to a desired particle size and is discharged through metering bar grids at the bottom of the tank.

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

An inching drive is used as an auxiliary system to the main drive for a large machine such as a ball mill, industrial kiln, conveyor, or elevator. Its purpose is to turn the equipment at a speed slower than the normal operating speed — typically 1 to 2 rpm, although fractional rpms are also common — and to do so at high torque — typically 120 percent of the normal drive torque.
