Abstract: An assembly for abrasive agent recovery in water jet cutting units including a separator (4) for separating usable abrasive agent from sludge and water and a drying oven (9). A conveyor (6) follows the separator (4) for transporting the overwhelmingly usable abrasive agent separated in portions by the separator (4) and compression rollers (30) adjacent the conveyors press remaining water out of the portions located on the conveyor. The portions on the conveyor are blown by a compressed air unit (8) and a spraying nozzle into the drying oven (9), through which warmed exhaust air, further heated in the drying oven (9), flows. The drying oven (9) consists of a climbing shaft (12), closed via a heater (10) with a screen (11), an eddy chamber (16) connected to a funnel (17) to the lower end the eddy chamber (16), a line (18) from the eddy chamber (16) to a catching tank (19), and a suction connection (20).
