Abstract
Uniform spherical granules are produced from powder raw material without utilizing an agglomerating liquid by repeatedly and alternately compacting a dry powder raw material within a granulating vessel to cohesively form agglomerates of the material and fluidizing the powder material within the vessel to break up and form the agglomerates gradually into a uniform spherical shape.
