Abstract

Apparatus and method for the heat processing of granular materials by the counterflow of the granular material and preheated particulate heat exchange media through a processing drum rotatable about an inclined axis. The hot media is imtimately mixed with the granular material internally of the drum to heat the material and to cool the media. Various arrangements are disclosed to recover the heat imparted to the material, or to utilize the media for successive heating operations, or to recover waste heat from other related heat processing operations or to utilize the material as preheated by the media.
