A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.The raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect upon the ...

2.Vibration grain separator has low noise, low energy consumption. 3.Vibration grain separator has stable operation, good cleaning effect and high production efficiency. 4. Vibration grain separator is driven by vibration motor, the exciting force, vibration direction and screen inclination can be adjusted according to needs.

The raw materials are fed into the grinding chamber through the hopper of the screw feeder, cut by the high-speed cutter, and then sucked into the cyclone separator and bag filter by negative pressure. The discharged material meets the product requirements.

In the OK mill, parameters, such as mill air flow, separator speed and grinding pressure, can be easily adjusted during operation to control or alter the PSD curve to a profile (steeper or flatter) that achieves the desired quality standards. When needed the PSD curve can match that from an existing ball mill. Handle multiple materials with ease
