Gebr. Pfeiffer to supply 10 more mills to Shree Cement Ltd. in India
The Kolkata-based company Shree Cement, one of its best customers, decided to buy 10 more mills from Gebr. Pfeiffer. This deal continues the company’s expansion strategy to distribute several cement works (greenfield and brownfield) across the whole of India and to produce cement in stand-alone grinding terminals.
For the cement works, Gebr. Pfeiffer will supply MVR 6000 R-6 raw mills with capacities of about 550 t/h and an installed drive power of 6700 kW each. Moreover, these works will come equipped with coal mills of the type MPS 2800 BK, each featuring a 720-kW drive and an integrated high-efficiency classifier of the type SLS BK. Cement mills of the type MVR 6000 C-6 are planned to grind clinker and extenders in these cement works and/or stand-alone grinding terminals.
The mill types described are in successful operation at several of Shree Cement’s locations and these repeatedly ordered mills reflect the satisfaction of the customer, who is currently running 24 Pfeiffer mills.
The MVR mill with its six actively redundant grinding rollers has proven particularly successful for the finish-grinding of cement. Compared to other combined grinding systems, previously used by this customer, this system allows significant savings on electrical energy. In addition, the high level of availability of Pfeiffer mills played a key role in the customer’s purchasing decision.
The plants planned for cement grinding, using the MVR 6000 C-6, are to alternately produce 300 t/h of Ordinary Portland Cement (OPC) at a product fineness of 3100 cm²/g acc. to Blaine or 300 t/h of Portland Pozzolana Cement (PPC) containing as much as 35 % of fly ash at a product fineness of 3500 cm²/g acc. to Blaine or 180 t/h of ground granulated blast-furnace slag (GGBFS) at a product fineness of 4500 cm²/g acc. to Blaine. Each of the mills will come equipped with a 6700-kW drive.
While Gebr. Pfeiffer SE will supply the core components of the mill and the gear units from Europe, its Indian subsidiary, headquartered in Noida, Gebr. Pfeiffer (India) Pvt. Ltd., will provide the components such as the housings of the mills and classifiers, the steel foundation parts as well as the internal parts of the classifiers. In addition, the Indian subsidiary will design the plant layout and advise the customer on the equipment he will procure on his own.
