This book will become a benchmark for the study of rotary kiln phenomena, for the design of new rotary kiln processes, and for the modeling and analysis of existing processes. It will be an indispensable addition to the bookshelves of engineers in the cement, lime, pulp and paper, and mineral industries. It will prove invaluable to researchers

The shaft kiln in a modernized form is still used in some countries, but the dominant means of burning is the rotary kiln. These kilns—up to 200 metres (660 feet) long and six metres in diameter in wet process plants but shorter for the dry process—consist of a steel, cylindrical shell lined with refractory materials.

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.

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 environmental ...

lining of rotary kilns that are used to improve heat transfer. The first feature is a set of lifters that are installed in the cold end of the kiln, usually just downhill from the chains. Lifters mix the lime mud and expose it to the hot gases. Discharge dams are usually located at the hot end of the kiln and cause the lime to pool behind the
