1,400˚C in a long rotary kiln. It is then interground with gypsum and other cementitious materials to produce cement. Producing the high temperatures necessary to drive the reaction requires a great deal of energy. Kiln fuel accounts for roughly 86% of all energy required in the

RAW MATERIALS Burning the mix

kiln requires additional length (in comparison to a dry kiln). Additionally, to evaporate the water contained in the slurry, a wet kiln consumes nearly 33 percent more kiln energy when compared to a dry kiln. Wet-process kilns tend to be older operations as compared to dry-processes where raw materials are fed into the process as a dry powder.

The cement kiln

ation on average burns the kiln feed. Reasons for variations in burnability could be insufficient raw mix control and/or homogenisation of the kiln feed. The resulting clinker will vary in free lime con-tent, and the normal reaction from kiln operators is to burn harder and eventually operate the kiln on the 'hot side' to avoid To 700˚C

Rotary Kiln

Cement - Cement - Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.
