Loesche wins VRM order for Objana's Line 5

Loesche is delivering two vertical roller mills (VRM) for Dangote Cement's Obajana plant's new line in Kogi State, Northern Nigeria. With a total capacity of more than 12Mta, this plant is currently not only the largest cement plant in Nigeria but also the largest cement plant in sub-Saharan Africa.

Loesche's order for the new Line 5 in Obajana comprises a high-performance six-roller mill for cement raw meal with a capacity of 580tph – the largest roller mill for raw material in the Loesche range. The order also includes a large three-roller mill with a modular design featuring a drive power range of 1000kW for grinding hard coal and lignite with a throughput of up to 70tph.

In addition to the two complete VRMs, Loesche's scope of delivery comprises the respective classifiers for the type LDC for cement raw material and the type LSKS ZD coal mill, which is characterised by individually adjustable grain size separation. The two mill gear units are equipped with state monitoring and remote access for remote monitoring.

Moreover, Loesche is contributing to the design and planning of the entire plant as well as the engineering for the electrical measurement, control and regulation technology and complete automation. The delivery date is scheduled for the third quarter of 2018.

The raw material mill is equipped with the highly-resistant metalmatrix-compound (MMX) technology which guarantees a very long service life.

The contract partner for this project is again the Chinese company Sinoma International Engineering Co, Ltd, which has already installed a total of seven clinker and cement raw meal VRMs for the Obajana plant in close cooperation with Loesche in previous years.
