A roller conveyor or conveyor-classifier assembly is disclosed which comprises a plurality of rollers (16), a corresponding bearing support block (18) for each end of each of the rollers (16), with each block (18) being of upper case 'H' configuration in transverse cross section to define an upper and lower groove (18U and 18L in FIG. 6), and including frame (25) for supporting the blocks (18). The frame assembly (25) comprises oppositely disposed rails (22A, 24A) each having a track (22B, 24B), respectively, adapted to slidably project into oppositely disposed grooves (18U, 18L) in bearing support blocks (18). Shims (36) which are lower 'h' configuration in transverse cross section, are insertable from the outboard sides of the frame assemblies (25) and are interposed between adjacent bearing support blocks (18) with the lower portion (36A, 36B) of the 'h' configuration being adapted to interlockingly straddle the upwardly projecting lower track (24B) for retention in position to provide a predetermined spacing between the adjacent bearing support blocks (18), and thus, to provide a predetermined clearance or spacing between adjacent rollers (16) supported by the adjacent bearing support blocks (18).

Roller conveyor-classifier

Reversible rotation grinding mills having a radially compartmentalized discharger with direction and volume control to laterally extending screens so as to obtain a constant 'cut' of material or slurry flow to stabilize the volume and size consist of the discharge.
