This type of kiln with grate preheaters were developed by O. Lellep and the company Polysius; thus, these kilns are called Lepol kilns (Locher, 2000, p 58). The production capacity of this process is between 100 and 3,000 t/d. iii. In the semi-dry process, dry raw meal is pelletised with water and fed into a grate preheater before the kiln.

The use of drilling wastes and muds is most preferable in cement kilns, as a cement kiln can be an attractive, less expensive alternative to a rotary kiln. In cement kilns, drilling wastes with oily components can be used in a fuel-blending program to substitute for fuel that would otherwise be needed to fire the kiln.
The rotary kiln systems of the cement industry destroy these trace components virtually completely. [citation needed] Polycyclic aromatic hydrocarbons (PAH) PAHs (according to EPA 610) in the exhaust gas of rotary kilns usually appear at a distribution dominated by naphthalene, which accounts for a share of more than 90% by mass.

In the preheater, the kiln feed is preheated by hot gas coming from the combustion chamber and rotary kiln. Then the preheated kiln feed is partially calcined (made powdery) in a combustion chamber and riser duct and then completely calcined in a rotary kiln as well as heated to approximately 1400 C to form clinker components C3A, C4AF, C2S ...
Structured into fourteen chapters, this volume covers various aspects of kiln maintenance and deals with the wear of components, operational parameters and their impact on the condition of the kiln, maintenance-friendly design considerations of kiln components, on-line techniques for condition monitoring, repair during operation, effective management of a kiln shutdown, and some management ...
Heat Recovery from Rotary Kilns - Heat recovery system. A heat recovery system that captures heat lost from rotary kiln surfaces in cement, paper and sponge iron plants and putting it to useful work. The outside surface temperature of the kiln ranges from 200-300°C.
The rotary cement kiln process is intrinsically unstable, there are long time delays and large perturbations acting on it. The control problem consists of maintaining a given temperature profile along the kiln plus obtaining good burning conditions.
