The present invention relates to an apparatus for separating into two components the stone and sand mixture which is a byproduct of ordinary rock crushing operations for example at a quarry. More specifically, the inventio n relates to a forwardly inclined cylindrical drum which is simultaneously rotated and vibrated to separate the sand and stone mixture into a stone component a nd a sand component according to size. The stone and sand mixture is deposited by a conventional conveyor into the intake opening of the drum where the san d component is mechanically moved through the perforations of the drum while t he stone component traverses the drum exiting at the exhaust opening. Two additional conventional conveyors integrated into the operation of the apparatus transport the separated components away from the drum.
