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

The mill heights can be varied to optimize the media load and power input for specific applications Chamber volumes range up to 50 000 liters with corresponding drives ranging up to 6 500 kW The HIGmill is the only ultrafine grinding technology in commercial use that can use small size high density grinding media in mill sizes above 3000 kW

The quality of powder of non metal materials directly relates to the force exerted on grinding roller while the force on grinding roller relates to the thickness of the material layer The uneven pressure distribution between the roller and material layer is caused by the drum shaped characteristics of vertical mill grinding roller This paper studies the pressure distribution of roller in
