India: Shree Cement has ordered two vertical roller (VR) mills from Germany-based Gebr. Pfeiffer for the upcoming clinker line at its Raipur cement plant in Chhattisgarh. The supplier says that one of the mills will grind raw materials and the other will grind coal.

A MVR 6000 R-6 type raw mill will grind 800t/hr of raw material and have a drive power of 8700kW. Gebr. Pfeiffer said, “The grinding rollers of this mill can be equipped with roller tires for raw meal grinding as well as for cement grinding, provided that they have been designed according to the same force module. This saves money, because the identical components of rollers, tensioning system, roller arms, etc. mean that customers can reduce their spare parts inventory, since the same spare parts can be used for a raw meal mill and for a cement mill.” The mill will be equipped with an SLS 6000 VR high-efficiency classifier.

A MPS 2800 BK type mill will be used to grind coal with a capacity of 28t/hr, a drive power of 720kW and be “equipped with the latest design of the integrated SLS 2900 BK high-efficiency classifier optimised for MPS mills.”

The supplier said, “While the core components of the mills as well as the drive units will be supplied by Gebr. Pfeiffer from Europe, the Indian subsidiary Gebr. Pfeiffer (India) will provide components such as the mill and classifier housings, the steel foundation parts as well as internal parts of the classifiers.”
