Odra cement works orders new VRM, Poland

Gebr Pfeiffer has been awarded the contract to supply a MPS 3070 BC vertical roller for grinding 46tph of blast-furnace slag for the Odra works situated in Opole, Poland.

The slag, ground to 3800cm²/g Blaine, is intended to be used as an additive to the cement. The ordered vertical mill features a main drive with an output of 1350kW for the production rate of 46tph.  Exhaust gases produced by the clinker cooler allow the slag to be dried from nine per cent feed moisture down to <1 per cent residual moisture while being ground in the mill. The design of the mill also makes it possible to grind as much as 45tph of cement (OPC) to a fineness of 3500cm²/g Blaine.
