The ground coal is picked up by an air stream entering the mill through a Port Ring on the periphery of the Grinding Table; • Air entering through the Port Ring creates a fluidising zone in which 'heavy material' (Mill Rejects) such as rock falls through the Port Ring into the Air Plenum below the Grinding Table and is ejected from the Mill through the Mill Reject System;

Mining coal. Coal miners use large machines to remove coal from the earth. Many coal deposits, called coal beds or seams, are near the earth's surface, but others are deep mining methods allow coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour than in 1978.

Coal has been the main stay of Portland cement production and remains so with coal providing around 90% of the energy consumed by cement plants around the world. It takes 200450 kg of coal to produce 1 ton of cement. In 2015 the cement industry consumed around 4% of global coal production, around 330 Mt/year (Global Cement, 2016).

A coal mill is also called a coal pulverizer or coal grinder. It is a mechanical device used to grind raw coal into pulverized coal powders. The most used coal mills in cement plants are airswept ball mills and vertical roller mills. At present, most cement plants use coal as the main fuel in the clinker production process.
