Composition and preparationEdit. Tricalcium aluminate and calcium aluminoferrite are other common components. These components are often generated in situ by heating various clays and limestone. Portland cement clinker is made by heating a homogeneous mixture of raw materials in a rotary kiln at high temperature .

May 11, 2015Cement Manufacturing Plant Construction. Air is drawn first through the cooler and then through the kiln for combustion of the fuel. In the cooler the air is heated by the cooling clinker, so that it may be 400 to 800 C before it enters the kiln, thus causing intense and rapid combustion of the fuel.

A typical long-term-mean refractory consumption of a wet process kiln would be in the range 1-2 kg per tonne of clinker made, so the refractory was still a significant running cost. With the advent of more efficient dry processes, and particularly precalciners, the relative cost of refractories has been reduced, mainly because of the larger output that can be obtained from a given sized kiln tube.
