ABSTRACT:
A granulation apparatus in which a conical chamber having a downwardly and outwardly inclined wall is provided for collecting cut granules. The wall is covered with a flowing, circulating film of water, such film being of uniform thickness and circulating quickly. An annular water channel is provided around the cylindrical or conical chamber for collecting the granules, the annular channel being fed through a tangential water inlet. A flat, annular horizontal acceleration chamber is disposed in the upper region of the annular channel and communicates with the channel through an annular aperture formed in the upper radially outward region of the annular channel. At its radially inner periphery the acceleration chamber communicates with the chamber through an annular aperture.
The disposition of the inlet, the channel and the acceleration chamber cause water flowing into the chamber to be subjected to centrifugal force whereby the film of water remains closely adjacent the wall and is of uniform thickness.
