New grinding equipment for Douala
For the new cement grinding terminal Douala in Cameroon, Sinoma International Engineering Co. Ltd (NCDRI) has decided in favour of a new VRM from Loesche for this project. A Loesche mill of the type LM 53.3+3C will grind clinker with components such as gypsum, limestone and puzzolana. The product rate of clinker type CEM I A-L 42,5 will be 155-168 t/h at 3200 Blaine while the product rate of clinker type CEM II 32,5 will be 230 t/h at 3600 Blaine. The mill motor capacity for the LM 53.3+3C is 4600 kW. To cope with the extremely high feed moisture, the mill feed is separated into a dry string (clinker and reject) and a wet string (puzzolana and gypsum). Additionally to the mill Loesche will deliver metal detectors and mill rotary feeders. The supply is a split-up of Loesche key parts and a Chinese manufactured portion arranged by Sinoma International under supervision of Loesche. Delivery is scheduled at the beginning of 2014.
