Bolu Cimento Sanayii AS, a member of the OYAK Group, has ordered three vertical roller mills from Gebr Pfeiffer SE for a new production line in Kazan, Ankara. The cement producer already operates a grinding plant at the site which it is now expanding into a fully integrated facility.

The mills are scheduled to be delivered to the customer in the summer of 2014, boosting the number of Pfeiffer mills installed at cement plants owned by the OYAK Group to eight.

An MPS 4500 B with a drive power of 3150kW will be used for cement raw material grinding. The mill is guaranteed to produce 320tph at a product fineness of 12 per cent residue on the 0.090mm screen.

Pet coke and lignite will be ground in an MPS 225 BK vertical roller mill with a drive power of 400kW. The throughput rate of this mill when grinding pet coke will be 20 t/h at a fineness of 3 % residue on the 0.090mm screen and 35tph when processing lignite.

Bolu Cimento also opted for the Pfeiffer mill technology for cement grinding, ordering a mill of the type MPS 4500 BC with a drive power of 3300kW. This mill will yield 130tph of CEM I at a specific surface of 3900cm²/g acc. to Blaine.
