Abstract
A hog granulator for plastic material in which a plurality of longitudinal knives are arranged on a rotor inside a cutting chamber to engage in a cooperative cutting action with bed knives on the cutting chamber walls. A plurality of spaced, longitudinal pockets in the peripheral surface of the rotor bring cooling air to the cutting surfaces, and ribs are arranged across these pockets to reduce power requirements by preventing excessively large pieces of plastic material to be reduced from being received into and taking up residence in these pockets.
