Progress with Grinding Aids for Vertical Roller Mills
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 indies more internal circulations and more fines. As a result of the higher ΔP mill, the mill vibration increases (810mm/s ...
Vertical mills · Christian Pfeiffer
Vertical mills Flexible mills with integrated separator. The vertical mill enables high energy economy, and convinces with low specific wear values. Drying of the feed material, grinding, separating, and material transport take place inside the mill. It is thus especially well suited for grinding products with high proportions of wet components.
