Coal, raw meal grinding with vertical grinding accounted for more than 90%, cement clinker and slag grinding with vertical grinding are growing, which in modern cement plant in. Vertical mill has become the factory process of heavy equipment , it is a series of excellent characteristic place decision, a part of the pure mechanical technology, the other is part of the process, as follows:
( 1 ) the vertical structure, small occupation area.

( 3 ) the mill running low noise: the main source of noise from the motor and reducer, transmission for system and sealing air fan.
( 4 ) vertical mill air with low noise and low vibration, mining by rocker separate control roll, using a mechanical stop or hydraulic control roll can reduce noise and vibration while preventing the grinding roller and the grinding disc lining board made of metal contact.
