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.
Our products sell well all over the world, and have advanced technology in the field of crushing sand grinding powder.
The main motor is connected to one side of the gear unit while the auxiliary drive is connected to the other side. The pinion at the mills girth gear can be connected via a double
