Ball Mill (Ball Mills Explained) - saVRee - saVRee
The motor is usually fitted with a variable speed drive (VSD) to control the rpm of the ball mill. Gearbox – used for speed reduction from the motor to the ball mill. Balls – usually manufactured from manganese alloy steel , but the material depends upon for what material the mill will grind ( chrome steel alloy and rubber also available).

Inching drives – one way to improve mill safety - Metso
2022.4.11 Ignoring mechanical losses in this drive train, the power transmission at each stage, defined as torque x speed, is constant. The typical mechanical inching drive motor speed is around 1500 to 1800 RPM while the mill inching speed is in the order of 0.1 to 0.15 RPM. Thus, the gear reduction ratio between the inching drive motor and the
