Abstract: An improved centrifugal pneumatic comminutor including a housing containing a fan means operatively connected to a motor means, said housing having an inlet opening aligned with the axis of said fan and an outlet opening on the perimeter of said housing, an input conduit mounted to said housing surrounding said inlet opening including a frustal conically shaped section adjacent said housing, and an output conduit attached to said housing surrounding said outlet opening, the material to be comminuted being introduced into said input conduit and being drawn into said frustal conically shaped section by suction of said fan. The materials are comminuted in said iput conduit in a rotational impact area directly below said fan and thereafter are pulled through said fan and forced out said output conduit by the pressure of said fan. The fan means includes a ring member attached to the fan which rotatably mates with a journal means attached to the housing creating an air lock through the comminutor.
