ABSTRACT:
A wet-blast machine (1) with a closed-cycle re-use system (2) incorporates apparatus (3) for conveying loose particulate (abrasive) wet-blast material (4) present in a body of water (5). The apparatus (3) comprises a longitudinally extending trough (6), for containing the water (5) and particulate material (4), a support structure (7) movable in a reciprocating manner within the trough (6), and a row of longitudinally spaced flap members (8) attached to and depending from the support structure (7). When the support structure (7) is reciprocated, wave motions are created in the water (5), which move the loose particulate material (4) in a predetermined direction along the trough (6), namely toward a collection point provided by a chute (10).
