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.
