INFLUENCE OF MILL VENTILATION ON GRINDING EFFICIENCY

The reason why closed-circuit grinding is far more economical than open-circuit grinding is the coarser material in the closed-circuit grinding mill. By ventilation of mills, ground material is drawn out from the mill with the ventilation air, the material remaining in the mill thus becoming coarser, which improves grinding economy.

The cement mill - Understanding Cement

In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding. Gypsum is interground with the clinker in order to control the setting properties of the cement.
