LafargeHolcim orders MVR 2500 C-4 for Guinea
A Gebr. Pfeiffer mill will soon be used to grind cement in Guinea in West Africa. It is an MVR 2500 C-4, which will be set up at LarfargeHolcim’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 t/h of CEM IV 32.5 and 69 t/h 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 (compared to Gebr. Pfeiffer’s largest sold mills to date with a diameter of 6.7 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 50-60 %. 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.
