    Product quality is a function of cement particle size distribution (PSD) and the dehydration of the gypsum within the cement. 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 theVertical roller mill Wikipedia,Vertical roller mill is a kind of grinding machine for cement, raw material, cement clinker, slag and coal slag. It has the features of simple structure and low cost of manufacture and use. Vertical roller mill has many different forms, but it works basically the same.

    ment separator mill for cement The mill shell is divided by a diaphragm. Coarse grinding using big balls of up to 100 mm in diameter takes place in the first com- partment. The peripheral wear lining is designed as a lifting or activator plate lining which, with the large balls, achieves a OK™ cement mill The most energy- efficient mill for cement,finish grinding of Portland cement, slag and blended cements. The mill consistently uses five to ten percent less power than other cement vertical roller mills, and in comparison with traditional ball mill operations, the energy requirements for the OK cement mill is 30-45 percent lower for cement grinding and 40-50 percent lower for slag.
