Cement Kilns: Clinker

On extracting clinker from below a conical pile, "rat-holing" takes place, producing a uniform blend of the variable layers of clinker laid down during the building of the pile. In practice, this is effective for blending out both short-term and medium-term variations. Of course, a minimum of two piles or silos is required for this.

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.
