Cement Kilns: Clinker Thermochemistry

The large scale of the reactions endotherm means that this stage of the process takes up a major part of the cement kiln, and the efficiency with which the reaction is achieved is a major factor in defining the output and heat consumption of the kiln.

Cement kiln - Wikipedia

heating the rawmix to sintering temperature (up to 1450 °C) in a cement kiln; grinding the resulting clinker to make cement (see Cement mill). In the second stage, the rawmix is fed into the kiln and gradually heated by contact with the hot gases from combustion of the kiln fuel.

The cement kiln - Understanding Cement

Manufacturing - the cement kiln. Most Portland cement is made in a rotary kiln. Basically, this is a long cylinder rotating about its axis once every minute or two. The axis is inclined at a slight angle, the end with the burner being lower.

Cement - Wikipedia

Most cement kilns today use coal and petroleum coke as primary fuels, and to a lesser extent natural gas and fuel oil. Selected waste and by-products with recoverable calorific value can be used as fuels in a cement kiln (referred to as co-processing), replacing a portion of conventional fossil fuels, like coal, if they meet strict specifications.

Portland cement - Wikipedia

Portland cement clinker is made by heating, in a cement kiln, a mixture of raw materials to a calcining temperature of above 600 °C (1,112 °F) and then a fusion temperature, which is about 1,450 °C (2,640 °F) for modern cements, to sinter the materials into clinker.
