ABSTRACT:
A syringe and needle grinder incorporating a cylindrical-shaped rotor cutting device which is rotated within a stationary housing having an intake duct in the top of the housing offset from the center of rotation of the cutting device and a discharge duct in the bottom sidewall of the housing. The first set of cutting blades extend radially from the hub of the rotor and a second set of cutting blades are longitudinally positioned around the periphery of the rotor which act in conjunction with a plurality of stationary blades on the inside of the housing to further grind and shear the material prior to expelling it from the discharge opening.
