During the work of limestone rod mill, the motor drives through the reducer and surrounding gear reducer, to drive the cylinder to rotate. There are suitable grinding media-steel bars in the cylinder body. Under the centrifugal force and friction force, grinding medium will be elevated to a certain height, and then fell in purging fall state.
