Raw mills for all requirements | Gebr. PfeifferGrinding, drying, and classifying in one machine. Depending on its deposit and composition, the cement raw material may contain a more or less big portion of water. Especially with high feed moistures, drying is of particular importance because the existing surface moisture has to be evaporated almost down to zero in the.raw grinding mills,latest technological innovations in grinding with the vertical roller millAny design detail of a grinding unit should follow this philosophy. With the innovative COPE drive and the “4+4” cement mills and 6-roller raw mills in combination with a common parts concept covering both of the mill types, the technical and commercial risks derived from single grinding unit solutions are significantly.
