ABSTRACT:
There is disclosed a method and apparatus for treating particulate material. The said material is injected into a chamber. The material subsequently thereto is sprayed with a moistening material. At the same time gases are introduced at the top of the chamber and at the bottom thereof whereby the moisture on the particulate material is evaporated at a controlled rate. The parameters are such that the applied moisture has an opportunity to penetrate the particulate material for a short period of time to achieve some agglomeration before the moisture is evaporated. A fluidized bed is maintained at the bottom of the chamber and the treated particulate material is removed in this fashion.
