Aug 30, 2012 Kiln is heating up from the exit side by the use of natural gas and coal. When material reaches the lower part of the kiln, it forms the shape of clinker. Cement Manufacturing Process Phase V Cooling and Final Grinding. After passing out from the kiln, clinkers are cooled by mean of forced air.
The rotary kiln is made up of steel tubes having the diameter of 2.5-3.0 meter and the length differs from 90-120meter. The inner side of the kiln is lined with refractory bricks. The kiln is supported on the columns of masonry or concrete and rested on roller bearing in slightly inclined position at the gradient of 1 in 25 to 1 in 30.

The early commercially successful rotary kilns in Britain were nearly all straight cylinders, the exceptions being those at Norman 1904. Lengthening of the early kilns at Wouldham and Bevans resulted in kilns with enlarged burning zones, while the lengthened kilns at Swanscombe had enlargements at both ends. Among new installations from 1909 to 1914, only 15 out of 44
Aug 24, 2015 9 Rotary Kiln Processes With the arrival of rotary kilns, cement manufacturing processes became sharply defined according to the form in which the raw materials are fed to the kiln. Raw materials were either ground with addition of water, to form a slurry containing typically 30-45 water, or they were ground dry, to form a powder or raw meal .
A. A Boateng, in Rotary Kilns Second Edition, 2016. 10.4 The Cement-Making Process. Rotary kilns are synonymous with cement making, being the workhorses of this industry. There are many types of rotary kiln arrangements for producing cement clinker with each incremental design goal aimed at improving energy efficiency, ease of operation, and product quality and minimizing
