Abstract

A rotary kiln (10) is employed which is inclined downwardly from its charge end (12) to its discharge end (14) and has a maximum length to breadth ratio of 5:1. The interior space of the kiln (10) is heated by means of at least one burner (B1, B2) directed into the kiln from one end thereof to a substantially constant elevated process temperature. Material is fed into the kiln (10) so that it occupies a maximum of 10 % of the cross-sectional area the interior space of the kiln at the charge end. Upon entering the kiln the material is subjected almost immediately to the required process temperature. As it moves along the bottom of the kiln from the charge to the discharge end, heat transfer to the material is primarily by radiation from the combustion space and from the lining of the kiln. <IMAGE>
