At the end of June 2007 GEBR. PFEIFFER AG received an order from Cementownia Warta S.A. to supply a cement raw mill. This recent order is a repeat order of the MPS 4000 B vertical roller mill supplied in 1999. The mill type chosen for the required cement raw meal capacity of 240 t/h at a fineness of 12 % R 0.090 mm is again an MPS 4000 B. Compared to the mill in operation, which is fitted with a 1,250-kW drive and producing the same capacity, this mill will come equipped with a 1,600-kW drive due to a poorer grindability being expected for the future cement raw material.
