22 May, 2019. The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force. At a certain height, it will automatically ...

The grinding wheel rotates quickly thanks to an electric motor or other power source. This rotation allows the abrasive particles to come into contact with the workpiece, making it easier to remove material. Grinding Operation: The operator guides the grinding wheel over the surface of the workpiece, applying pressure as necessary.
