Abstract
An apparatus and method for desegregating and conveying aggregate. A drag slat conveyor 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. The larger and smaller aggregate are thereby reoriented 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.
