Loesche biggest VRMs for Obajana 4

On behalf of Dangote Industries the management of Sinoma International Engineering Co. Ltd (NCDRI) placed another order for Loesche vertical roller mills for the cement plant Obajana 4. Having delivered equipment for Obajana 3, Loesche has now been awarded a contract for Obajana 4. Sinoma International Engineering Co. Ltd (NCDRI) who has for many years been a customer in favor of Loesche Mills has once again decided for Loesche’s vertical roller mills.

Three Loesche Mills will be included in the process: for the raw material grinding plant one Loesche Mill Type LM 69.4 will be installed for the grinding of cement  raw material at a product range of 450 t/h (max. 540 t/h) with a fineness of 10 % R DIN 0,09 mm. The mill motor capacity for the LM 69.4 will be 4300 kW. Clinker with components such as gypsum and limestone will be ground in the two Loesche Mills Type LM 63.3+3C to be erected in the clinker grinding plant. The product rate of clinker type CEM I A-L 42,5 will be 310 t/h at 3200 Blaine while the product rate of clinker type CEM II 32,5 will be 335-360 t/h at 3200 to 3500 Blaine. The mill motor capacity for the three LM 63.3+3C will be 6300 kW. In this project, as for the project Obajana 3, the high wear rate of the cement raw material had to be considered when designing the mills as tailor-made solutions. In addition to the mills and the mill motors Loesche will deliver metal detectors and rotary feeders. The supply is a split-up of Loesche key parts and a Chinese manufactured portion arranged by Sinoma International under the supervision of Loesche. Delivery is scheduled for the end of 2013.
