ABSTRACT:
A granulator has a first coarse cutting stage operating at between 5 and 45 rotations per minute and a second fine cutting stage operating at two to ten times the speed of the first stage. Since granulate exiting the second stage is uniformly divided, the granulator operates independent of a screen. A first cutter stage has cutting segments having blades interspersed with deflector segments about a shaft. Rotation of the shaft urges the blades past a spaced stationary cutter.
