Guinea: LafargeHolcim Guinea has ordered a MVR 2500 C-4 vertical roller mill from Germany's Gebr. Pfeiffer for its Sonfonia cement grinding plant in Conakry. The cement mill will have a total drive power of 1300KW. It has been designed to grind 75t/hr of CEM IV 32.5 and 69t/hr of CEM IV 42.5 to a specific surface of 3440cm²/g and 3340cm²/g acc. to Blaine respectively.
It has successfully reduced CO2 emissions from 1.12 T CO2 per tonne of cement in 1996 to 0.719 CO2 per tonne of cement in 2010. What's more, some of the plants have thermal and electrical specific energy consumption (SECs) comparable to the best cement plants in the world, resulting in low emission intensities.

Vertical roller mill is a kind of grinding machine for cement raw material, cement clinker, slag and coal slag. It has the features of simple structure, low cost of manufacture and use.Vertical roller mill has many different forms, but it works basically the same.
The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time
