Belgium: Gebr Pfeiffer has received an order from Cemminerals to supply a grinding plant for slag and cement. The plant, in Flanders, will use a MVR 5300 C-6 type mill. The order was taken in December 2016 and the mill is scheduled for commissioning in early 2018.
The Pfeiffer MVR 5300 C-6 slag and cement mill will be used to grind five different cement qualities as well as pure slag to three different fineness degrees. The mill is guaranteed to achieve capacities of 132t/hour pure slag, ground to 5000cm²/g acc. to Blaine, and of up to 200t/hour CEM II, ground to a fineness of 3500cm²/g acc. to Blaine. The mill main drive is designed for an installed power of 4600kW, and the SLS 4750 BC high-efficiency classifier, mounted on top of the MVR mill, enables high material fineness degrees of up to 5000cm²/g acc. to Blaine.
In addition to the MVR mill the contract includes handling equipment, two in-feed devices to enable moist slag and dry clinker to be fed to the mill separately, the plant filter, the plant fan, the magnetic drum separator and all ductwork including chutes, expansion joints and the stack. The scope of supply also includes a hot gas generator for the heating of the mill, as well as all electrical drives, starters, frequency converters and the electrical switchgear.
