GLOBAL CEMENT: GRINDING Global Cement Magazine June 2018 - Reprint The differential pressure between the inlet and outlet of the mill (∆P mill) is an important process variable for the testing of grinding aids. ∆P mill reflects the load and the filling level of the mill. At unchanged separator settings, the increase of ∆P mill indicates
Vertical roller mills (VRM) have been used extensively for comminuting both cement raw materials and minerals like limestone, clinker, phosphate, manganese, magnesite, feldspar and titanium.
Over the last three decades the vertical roller mill has become the preferred mill for grinding of raw materials. The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system.
grinding of raw materials. The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system. However, despite these benefits, applications of the vertical roller mill for cement grinding are less prevalent.
