Loesche wins VRM contract for Dangote's new Ethiopia plant
Published: 25 January 2013


Loesche has been awarded a contract to supply four vertical roller mills for Dangote Cement’s new plant in Ethiopia by Sinoma International Engineering.

For raw material grinding, a Loesche Mill Type LM 69.6 will be installed for the grinding of cement raw material at a product range of 450tph (maximum 490tph) with a fineness of 10 per cent R DIN 0.09 mm. The mill motor capacity for the LM 69.6 will be 6000kW.

One Loesche Mill Type LM 28.3D will be implemented to grind local and imported steam coal. The product range of this vertical roller mill will be 50tph with a fineness of 12 per cent R DIN 0.09mm. The mill motor capacity for the LM 28.3D will be 800kW.

Clinker with components such as gypsum, limestone and pumice will be ground in the two Loesche Mills Type LM 53.3+3C to be erected in the clinker grinding plant. The product rate of clinker type CEM I A-L
42.5 will be 155-168tph at 3200Blaine while the product rate of clinker type CEM II 32.5 will be 230tph at 3500Blaine. The mill motor capacity for the LM 53.3+3C will be 4650kW.

Both the plant elevation of 2600m above sea level as well as the very poor grindability of the cement raw material were a special challenge for the layout of the grinding equipment.

In addition to the mills and the mill motors, Loesche will deliver metal detectors and mill rotary feeders. The supply is a split of Loesche key parts and a Chinese manufactured portion arranged by Sinoma International under the supervision of Loesche.
