Nigeria: Lafarge Africa Plc, part of LafargeHolcim, is erecting a new coal grinding plant at its cement plant in Ewekoro, Nigeria, with Germany’s Loesche GmbH as the supplier. The plant previously used natural gas as its main fuel but inadequate local supplies meant that a change to coal was necessary. The order was made by the project’s general contractor, China’s CBMI Construction Company.
Local lignite and petcoke will be used as grinding materials. The grinding capacity for coal is 23t/hr at 23% R90µm and for petcoke it is 16t/hr at 3% R90µm.
The engineering, the core components of the mill and of the classifier with central feed, the rotary gate and the mill gearbox with a nominal power of 450kW are all included in the scope of service. Naturally, the reliable coal mill type corresponds to the ATEX standard to ensure safe operation. This is in line with LafargeHolcim's declared goal, defining health and safety as an overarching value.
