This cylinder rotates around its axis and transmits the rotating effect to the balls. The material fed through the mill is crushed by the impact and ground as a result of the friction between the balls. The drive system can either consist of a central drive (central gear unit helical gear unit or planetary gear unit) or a girth gear unit with pinion design (central gear unit helical gear unit).
The inching drive, also known as a barring or auxiliary drive, is an important component of any mill or kiln installation. It is used for maintenance and inspection purposes, as well as an emergency auxiliary drive to keep kilns rotating when the main motor fails. This paper covers what data the end user needs to
