Abstract: A self cleaning bearing assembly for use in a dehydrator washer for particulate solids which comprises a feed reservoir for water and particulate solids and an inclined main screw conveyor having a projecting shaft lower end portion submerged in the reservoir. The bearing assembly comprises a housing having an end cap at one end and an opening at the opposite end in communication with the interior of the feed reservoir. The housing has its longitudinal center line coincident with the main screw conveyor and a stub shaft mounted on the end cap of the bearing assembly also has its axis coincident with that of the main crew conveyor and its shaft. The projecting lower end portion of the main conveyor shaft and the stub shaft are disposed with the stub shaft in radially spaced relationship within the main shaft and a sleeve bearing is disposed in the radial space between the stub shaft and the main shaft.

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.
