ABSTRACT:
Moistened powder and granular materials, such as produced by an extrusion granulator, are disintegrated into uniformly sized and shaped granules by an apparatus having a cylindrical housing and a working plate rotatably disposed in the housing in coaxial alignment with said housing, with an opening at the center of the working plate. A working fluid is introduced into the interior of the housing above the working plate through a wall of the housing and moistened powder and/or granular raw materials are supplied into the housing onto the working plate. The treated materials are discharged through the central opening in the working plate.
