From raw meal to cement grinding
Raw materials are transferred to bins with variable speed dosing scales. The flow of each is automatically controlled by an online analyser to ensure uniformity of chemical composition. The raw materials are fed to the four-roller vertical mill with a capacity of 465 tph, using a high-efficiency separator to reduce the mill’s specific consumption, and then to the 10 000 t homogenisation silo for the storage of the raw meal.
An airlift system is used to propel the raw meal from the silo up the 135 m, five-stage, two-string preheater tower, equipped with stack gas analysers at the chimney and at the entrance of the kiln. McInnis uses the latest technologies to control its air emissions to meet the emission levels prescribed by the US Environmental Protection Agency’s National Emission Standards for Hazardous Air Pollutants (NESHAP) – New Plant 2015.
