The ball mill diagram shows the main parts of a ball mill, including the feeding device, the cylinder, the discharge device, the hollow trunnion, the transmission device, the gear cover, the girth gear, the pinion, and the motor. The ball mill can be operated in a wet or dry way, depending on the material properties and the intended use.
The mill control system consists of a very sensitive microphone installed near the outlet from chamber 1 of the mill, at the point of impact of the grinding balls and as close as possible to the housing of the mill. The on the digital electronic ear should almost touch the housing of the mill.
