In December 2016, Gebr. Pfeiffer received an order from the Belgian enterprise Cemminerals NV for the supply of a grinding plant for slag and cement. The plant, which will see a Pfeiffer vertical roller mill of the type MVR 5300 C-6 installed, will be set up in Flanders, in the middle of Europe.
Besides the MVR mill, the contract encompasses the handling equipment, two infeed 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, 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.
The Pfeiffer MVR 5300 C-6 slag and cement mill, featuring 6 rollers, is the most advanced vertical roller mill available on the market. It will be grinding five different cement qualities as well as pure slag to three different fineness degrees. The mill is guaranteed to achieve capacities of 132 t/h pure slag, ground to 5000 cm²/g acc. to Blaine, and of up to 200 t/h CEM II, ground to a fineness of 3500 cm²/g acc. to Blaine. The mill main drive is designed for an installed power of 4600 kW, and the SLS 4750 BC high-efficiency classifier, mounted on top of the MVR mill, enables high material fineness degrees of up to 5000 cm²/g acc. to Blaine.
Gebr. Pfeiffer’s enormous expertise and vast experience in the field of efficient cement and slag grinding convinced the Belgium customer. Sophisticated maintenance concepts and the innovative MVR product in itself, representing the basis for highest availability, were also key factors in the decision to choose the Pfeiffer technology.
The mill is slated for commissioning in early 2018.
