Abstract: Apparatus and methods are discussed herein for safely and automatically removing blockages from a shredding apparatus. For example, the shredding apparatus discussed herein include features that force blockages out of the shredding apparatus while the shredding apparatus is operating in one direction, without hindering the shredding of materials when the shredding apparatus is operating in an opposite direction. Moreover, the features remain stationary irrespective of the direction at which the shredding apparatus is operating, reducing the risk of failure.

Abstract: A discharge station for a drag type conveyor system (10) includes a pair of spaced side rails (18, 20) and a series of elongated bottom panels (24) extending transversely of the rails. The bottom panels of the station are capable of lateral movement to adjustably define individual discharge openings (26) of selected size and configuration for each panel length. The particulate material (14) then is drawn along the successive panels to effect controlled uniform discharge of the particulate material through the discharge openings.

Abstract: A centrifugal separator includes a chip bowl for receiving a fluid-particulate mix and delivering the mix onto the screening surface of a cylindrical separator screen disposed around the bowl. A canopy portion of the bowl overlaps the separator screen and is axially positionable therealong such that a variable length of the separator screen may extend beyond the forward edge of the bowl. A separator drive shaft has an axial bore for housing a bowl drive column and an adjusting rod. The bowl drive column is mounted to the separator drive shaft and adjusting rod such that axial movement of the adjusting rod causes axial movement of the bowl drive column but not the separator drive shaft and rotation of the separator drive shaft causes rotation of the bowl drive column but not the adjustment rod.
