<p>The equipment disclosed comprises a plurality of nozzles (10) serving to flood the concrete mix prior to separation of the coarse aggregates by a first wide mesh screen (1); these aggregates are collected at a first recovery station (6), whereas the finer aggregates fall together with the water and cement into a first tank (2) below. The contents of this tank are maintained at a constant level, and fed by a pump (11) into a hydrocyclone (3), whereupon fine aggregates are separated from the water and cement, discharged by the cyclone outlet (4) onto a second, fine mesh screen (5) directly below, and conveyed toward a second recovery station (7), and the water and cement residue is routed into a second tank (8), agitated, and recovered at a third station (9). The method thus implemented is also claimed.</p> |
