Abstract
In an apparatus for producing and/or processing granules, pellets or other particulate materials, having a rotary disc tight within a chamber and means for providing an upward gas stream through a slot between said disc and the chamber wall as well as means for spraying a liquid or steam onto the particulate material and possibly means for introducing powder for use in a powder layering process, the flow patter of the particulate material, which is maintained in non-fluidized condition, is improved by gas injection towards the center of the chamber or disc. A more uniform product having desired properties is obtained and the capacity is improved. The gas injection enables upscaling of apparatus and method.
