<p>An aggregate washing machine 10, such as for reclaiming the constituents of unset concrete, features a screen 30 over which fluid aggregate passes under gravity, from a hopper 20, leaving separated out larger particles 34, on the topmost surface of the screen 30. Finer particles pass into a tank 40, and then into a cyclone or centrifuge device 70, which separates finer aggregate from the remaining fluid. The device may be used for reclaiming or recycling mixed but unset excess concrete from building jobs.</p> |
