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 to RPM. Thus, the gear reduction ratio between the inching drive motor and the mill is ...

Figure 3f: Clinker grinding mill The output from the mill produces both the required fine cement and partially ground coarse particles. A system incorporating an air separator through a bucket elevator and air slides separates the fine and coarse constituents. The coarse product will be returned back into the mill for further grinding.

Inching is used in various applications such as conveyor belts, and ball mills. Inching involves short thrust of motions at reduced power. A ball mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground.
