A Chipper/Hammermill is a machine used for reducing wood or other materials into smaller parts, such as chips or shreds.
The Chipper/Hammermill consists in a Universal Rotor inside an enclosure with loosely-attached knives for the cutting action. Material is fed in a way that shards move away from the feed aperture. A screen allows broken biomass to fall through while keeping larger pieces in the milling chamber until they sufficiently small to fall through the screen. A fan below the screen removes the milled material through a chute that can be oriented in an appropriate direction to allow collection of the hammer-milled matter.
