Abstract

A crusher for comminuting material between a rotatable material feeder in the form of a screw conveyor (4) and a number of substantially stationary anvils (3). The anvils (3) are arranged in a spaced, adjustable relationship relative to one another and relative to the screw, such that outlets (16) are formed between the anvils in order to successively discharge comminuted material during the feeding of the material along the screw. The direction of rotating of the screw is reversable, such that the material can be fed in any direction along the screw, thereby being successively comminuted and discharged through the outlets (16). Two press plates (19, 20) are arranged to feed the material under pressure sideways toward the screw (4). The plates are provided with cleaning iron plates (22) for scraping the outlets (16). The bottom of the crusher is swingable, so that the anvils (3) may be moved away, thereby enabling non-comminutable material to be discharged from the crusher. Each end of the screw is provided with a throttle ring (25) in order to reduce any discharge of material via the ends of the screw. The anvils (3) are provided with a cutting edge (14, 15) at each side of the screw.
