Vertical Roller Mills for Finish Grinding Industrial ...

Complete replacement of ball mills by vertical roller mills (VRMs) with an integral separator – as opposed to the use of VRMs as pre-grinding to ball mills – is regarded as a breakthrough. Use of VRM in finish grinding combines grinding and high efficiency classification and improves both energy efficiency and

how to improve grinding efficiency of vertical roller mill

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.
