Progress with Grinding Aids for Vertical Roller Mills

2021-7-8  The differential pressure between the inlet and outlet of the mill (ΔP mill) is an important process variable for the testing of grinding aids. ΔP mill reflects the load and the filling level of the mill. At unchanged separator settings, the increase of ΔP mill indicates more internal circulations and more fines.
