Abstract
A granulating apparatus particularly adapted for advanced ceramic materials having a granulation vessel with a cylindrical main body in which are coaxially-mounted rotatably an annular cage-like stirring rotor having peripheral stirring blades and a central impulse rotor having impulse blades and pins. The stirring blades are mounted in diverging pairs relative to their rotational direction to channel charge material axially centrally within the container, while the impulse blades are V-shaped convergingly in their rotational direction to impel charge material both radially and axially outwardly within the vessel, for enhanced charge material circulation. Nozzles mounted on the end cover of the vessel inject agglomerating liquid axially into the open granulation area between the rotors for direct impingement of liquid essentially only onto the charge material. The interior wall surface of the container, the stirring blades, and the impulse blades and pins have working surfaces formed of suitable wear resistant, non-contaminating material to facilitate use of the apparatus for advanced ceramic granulation applications.
