how to improve grinding efficiency of vertical roller mill

Air Volume Control. The differential pressure of the vertical roller mill is generally controlled at 5000~7000Pa to ensure the proper air volume. The change of the pressure difference within the mill is mainly affected by the feed amount when other conditions are constant. Therefore, the feed amount should be stabilized.
