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. Routine maintenance needs to be performed on ...
