The drum is mounted on an axis, and the entire assembly is placed on a foundation. The rotation of the drum is achieved through an electric motor, which generates the necessary rotational force. As the drum rotates, the grinding media tumble and collide with the material to be ground, causing the particles to break down and reduce in size.
