A desirably close clearance between outer edges of the flights of a conveying screw and the inside surface of a separator housing and screen can be obtained by offsetting the axis of the screw within the screen and by rotating the axis of the screw about the axis of the separator housing. Adjustments to the amount of such offset of the screw axis can be made in steps as the outer edges of the flights on the conveying screw wear. |
