ABSTRACT:
Herein disclosed is a particle processing apparatus to be used in a wide field including food, medical and chemical industries either for granulating or coating particles on a disk by rotating the disk in a barrel equipped with scrapers or for blending the particles in the barrel by rotating blades in the barrel. The particle processing apparatus comprises: a barrel for accommodating particles to be processed; a disk-shaped rotating member having an outer circumference of V-shaped section and including processing means for processing the particles in the barrel when the rotating member is rotated; rotating means for rotating the rotating member; and an annular bearing member having an inner circumference of V-shaped section for bearing the rotating member in a rotatable manner with a small gap between its inner circumference and the outer circumference of the rotating member. The inner circumference of the bearing member is formed with a multiplicity of air injection ports for injecting therethrough compressed air supplied from the outside into the small gap.
