ABSTRACT:
A method for desegregating and conveying aggregate includes reorienting aggregate from a side-by-side lateral orientation to a longitudinal orientation. The longitudinally oriented segregated aggregate may then be thoroughly desegregated in a second conveyor. Reorientation preferably occurs as the aggregate is conveyed along a drag slat conveyor which has a notch in the floor of its discharge end which causes larger aggregate at the lateral edges of the conveyor to drop out of the conveyor after smaller aggregate located between the lateral edges.
