Germany: Gebr. Pfeiffer SE has announced new orders for vertical roller mills (VRM) in Poland and Malaysia.
Pfeiffer has won the contract to supply a MPS 3070 BC VRM for grinding 46t/h of blast-furnace slag for the Odra works in Opole, Poland.
At the plant it is intended that slag ground to 3800cm²/g Blaine will be used as an additive to the cement. The VRM will feature a main drive with an output of 1350kW for a production rate of 46t/hr. Exhaust gases produced by the clinker cooler will allow the slag to be dried from a 9% feed moisture level down to below a 1% residual moisture level while being ground in the mill. The design of the mill will also make it possible to grind as much as 45t/hr of Ordinary Portland Cement to a fineness of 3500cm²/g Blaine.
In Malaysia Pfieffer has won a contract from KHD Humboldt Wedag for the construction of a 5000t/day plant. KHD is acting as a general contractor for an order from Straits Cement, a subsidiary of the Malaysian YTL Group.
Pfieffer is to supply the VRM for grinding cement raw material and coal. A MPS 4750 B raw mill is to be set up which can handle a capacity of 300t/hr of cement raw material ground to a product fineness of 12% R 90µm. The coal mill of the type MPS 2800 BK will be capable of grinding 35t/hr of coal.
