India: Emami Cement Ltd has made three recent orders for mills from Gebr. Pfeiffer. The first Gebr. Pfieffer mill is for its greenfield cement plant in Chhattisgarh, which is currently under construction. The second is destined for a standalone grinding unit in West Bengal. This order is currently being processed.
The latest mill order is for a grinding plant in Odisha. The order covers a MVR 6000 C-6 mill with an installed drive power of 6700kW. This mill will be capable of producing 335t/hr of ordinary Portland cement (OPC). The grinding plant will be designed in a way to allow fly ash cement and granulated blast-furnace slag to be ground to a fineness of 3800cm²/g and 4000cm²/g acc. to Blaine, respectively.
The MVR 6000 C-6 mill with is its six rollers has an actively redundant system. In case of an unplanned outage of one grinding roller, it allows the mill to continue in operation with four rollers while the roller swung out of the mill is being worked on outside of the mill. When it comes to cement grinding, where regular and planned maintenance works are scheduled for the regeneration of the grinding elements, this concept offers the customer the option to carry out maintenance works on two rollers outside the mill while at the same time cement can continue to be produced, albeit at a somewhat lower capacity.
Thanks to the modular design of the MVR mills, the essential components, such as bearings, seals of the grinding rollers and the tension system, as well as the gear units of the mill main drive, will be designed so as to be identical to the parts of the MVR mills that have been supplied to Emami Cement previously, i.e. an MVR 6000 R-6 and an MVR 6000 C-6. This will enable Emami Cement to manage with a small pool of strategic spare parts, which can be used with all the MVR mills.
Gebr. Pfeiffer SE will supply the core components of the mills and the gear units from Europe. Its Indian subsidiary, Gebr. Pfeiffer (India) Pvt. Ltd., will provide components such as the housing of the mill and classifier, the steel foundation parts as well as all static and dynamic interior parts of the classifier and, in addition, supply some of the equipment required to complete the grinding plant. Moreover, the Indian subsidiary will do the plant layout and advise Emami Cement on the equipment it must procure itself.
