Kolkata-based Shree Cement has awarded Gebr Pfeiffer (Germany) and its subsidiary Gebr Pfeiffer (India) Pvt Ltd a contract for five vertical roller mills.
Shree Cement is currently expanding its presence outside the Rajasthan market in the west, with the construction of a greenfield plant in the state of Chhattisgarh and a grinding plant in Bihar state to serve the east India market.
The new order comprises three type MVR 6000 C-6 cement mills, each with an installed drive power of 6700kW, a MVR 6000 R-6 raw mill (also with an installed power drive of 6700kW) and an MPS 3070 BK suitable for grinding petcoke and/or coal.
The Raipur works in Chhattisgarh will see an MVR 6000 R-6 for raw material grinding installed in addition to a cement mill. The mill, featuring a 6700kW drive, is designed to grind 500tph of raw material to a product fineness of two per cent residue on the 212µm screen, with the material being classified in the integrated high-efficiency SLS B classifier belonging to the latest generation. Moisture inherent in the feed material will be dried in the mill while the material is being ground by using waste gas from the cement rotary kiln.
The plants planned for cement grinding (to be equipped with the MVR 6000 C-6), are to alternately produce 270-300tph of OPC ground to a product fineness of 3100-3500cm²/g according to Blaine, or 270-300tph of PPC containing as much as 35 per cent of fly ash and ground to a product fineness of 3500-3800cm²/g accr to Blaine, or 180tph of GGBS with a fineness of 4500cm²/g according to Blaine.
The new contract brings the total number of Pfeiffer mills acquired by Shree Cement to 24, making it the German grinding specialists’ largest single customer.
