6.4.6.1 Preblending of coal. Cement plants receive coal from more than one source, and even from the same source of supply, there are wide fluctuations in the ash content. Such fluctuations upset the combustion, resulting in ever-changing burning zone conditions, loss of coating, higher heat losses and poor clinker quality.

Cement production begins with limestone, a sedimentary rock. Once quarried, it is mixed with a silica source, such as industrial byproducts slag or fly ash, and gets fired in a kiln at 2,700 degrees Fahrenheit. What comes out of the kiln is called clinker. Cement plants grind clinker down to an extremely fine powder and mix in a few additives.
