ABSTRACT:
This noise reducing device is arranged in the discharge chute of a material granulating apparatus in which a rapidly rotating knife cuts strips or strands of material into granules. In one embodiment of the device a wing wheel or impeller type of wheel is supported off-center for rotation in a portion of substantially cylindrical cross section of the chute. In another embodiment, angularly arranged plates are positioned substantially oppositely each other in the discharge chute to deflect the granular material so as to follow a zig-zag path.
