Abstract of the Disclosure An apparatus and method for treating and conveying hydrauli- cally mined aggregate the mined aggregate is separated into dry, relatively large aggregate pieces for dry conveyance and wet, relatively small aggregate pieces for wet conveyance. In the preferred embodiment, the method and apparatus provides for re- ducing any oversized large aggregate pieces in size so that the large pieces do not exceed a predetermined maximum size. Size reduction is provided by a mechanical breaker and wet, relatively small aggregate is separated out of the mined product prior to the breaking step. The apparatus is embodied in a feeder-breaker mechanism wherein a conveyor running lengthwise of the mechanism first subjects the total mined product to size separation or classification, then directs the larger aggregate pieces through the breaker and, finally, discharges the breaker tr?ated pieces to a dry conveyor. The separated wet, relatively small aggregate pieces are collected within the mechanism and pumped away.
