An MVR 2500 C-4 mill is to be set up at LafargeHolcim’s Sonfonia plant in the port city of Conakry. Featuring a total drive power of 1300 kW, the mill has been designed to grind 75 tph of CEM IV 32.5 and 69 tph of CEM IV 42.5 to a specific surface of 3440 cm2/g and 3340 cm2/g acc. to Blaine, respectively.
With the MVR 2500 C-4, the customer opted for Gebr. Pfeiffer’s current best seller. Despite the relatively small grinding table diameter of 2.5 m, the mill offers active redundancy.
This means that, in the unlikely event of a grinding roller failing, the mill can continue to be operated at a throughput rate of between 50% and 60%. Only the roller opposite the roller that failed must additionally be swung out – the other two rollers remain in operation.
The order for the mill was placed by the Chinese general contractor CBMI.
