Abstract
A method and apparatus in the context of a pellet former (10) that is integral to an annular gap extruder/expander (11). A housing (30) is disposed around the annular gap extruder outlet end. Material is received from annular gap (37) on the face of a rotating disc (14) and, upon expansion, is directed into a roller area (43) by feed plows (23) or a screw flight (42). Pellet rollers (24) rotatably mounted on the disc push the material through a ring pellet die (22) disposed around the roller area. Cut off knives (25) attached to the disc cut the material into pellets as it exits the pellet die.
