Abstract: A small mill is essentially composed of a feed chute (1) discharging onto a rotor (2) equipped with milling and/or cutting hammers (3) interworking with a milling housing (4) that is equipped with screening walls (5), a crusher element (6) that can be provided upstream from the rotor (2), above the feed chute (1) and at a distance from the latter. The mill is characterized in that the axis of the rotor (2) is inclined relative to the axis of the feed chute (1) by forming an acute angle with the latter. This mill can be applied more particularly in the field of processing materials of any origin, especially by shredding with crushers, hammer mills, or the like.

Abstract: A pre-grinder or pre-shredder apparatus, essentially made up of at least one drive unit (1) including a hydraulically or electrically driven motor (2), a reduction gear (3) and at least one shredding element (4) connected thereto and mounted on a frame (5), a wall, a feeder chute or any other mounting. The reduction gear (3) of the drive unit (1) of the pre-grinder or pre-shredder forms an element for attaching and supporting at least one shredder element (4) and is made up of a stationary portion (3?), attached directly to the frame (5) of the pre-grinder or pre-shredder or on a mounting or a wall of the latter, and by a mobile portion (3?), the shredder element (4) being inserted on the mobile portion of the reduction gear. The apparatus is useful in treating materials from any source, in particular by shredding using grinders, hammer mills or similar devices.
