India-based Sagar Cement Ltd has contracted Gebr Pfeiffer SE with another order for a mill to grind granulated blast furnace slag and granulated blast furnace slag cement.
A new 160tph of ground granulated blast furnace slag grinding plant forms part of Sagar Cement's extension to its Bayyavaram Village works, near to Visakhapatnam, India. To this end, Gebr Pfeiffer will supply its MVR 5000 C-4 mill which will be equipped with a 4300kW drive and four grinding rollers with active redundancy.
The grinding plant will be designed in a way that besides granulated blast-furnace slag with a fineness of about 4500cm²/g (according to Blaine) composite cements – with varying portions of granulated blast-furnace slag, fly ash and gypsum – can be ground in various finesses.
While the core components of the mill (ie, roller, tension system, grinding bowl and planetary gearbox) will be Pfeiffer-supply from Europe, the mill foundation parts (ie, housing and the integrated high-efficiency classifier of the type SLS 4750 BC) will be provided by Gebr Pfeiffer (India) Pvt Ltd, Pfeiffer’s Noida-based subsidiary. They will also supply most of the equipment required to complete the grinding plant, including plant fan and hot gas generator. Fired with coal, it will supply the heat required for drying the moisture contained in the granulated blast furnace slag.
Delivery is scheduled to be effected before the end of this year.
Sagar Cement was Gebr Pfeiffer's first customer in India, with the cement producer acquiring a mill to grind granulated blast furnace slag back in 1999. Some 18 years later, the 20tph mill is still running to the customer's "full satisfaction," Gebr Pfeiffer highlighted.
