Cement Kilns: Design features of rotary kilns

All rotary kilns essentially take the form of beams supported at a few points - the tyres (riding rings) - along their length, with the added complication that they rotate. The shell has to cope with all the forces involved, but is necessarily thin, since weight must be minimised.

Cement Kilns: Rotary kilns

With the arrival of rotary kilns in Britain in 1900, 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".

Cement Kilns: Early rotary kilns

With the arrival of rotary kilns, cement manufacturing processes became sharply defined as wet process or dry process. In the Wet Process, the kiln system is fed with a rawmix in the form of a liquid slurry, typically containing 30-50% of water by mass. In the Dry Process, the kiln system is fed with a rawmix in the form of a dry powder.

Cement Kilns: Long dry kilns

The kilns of Norman, Kirtlington, Southam, Premier and Ellesmere Port all had a common design: they consisted of relatively short kilns (L/D inside brickwork of 9-19) without any sort of internal heat exchanger, from which the hot dusty exhaust gases were ducted through a rotary raw material drier.
