A bulk material handling system and method use a horizontal boom frame supporting a conveyor mechanism for bulk material that is slidable relative to the horizontal boom frame. The conveyor mechanism is positioned such that, with bulk material received at a fixed location, or loading axis, on the horizontal boom frame, a portion of the conveyor mechanism will always be positioned to receive bulk material. The horizontal boom frame can also be made rotatable about the loading axis. By rotating the horizontal boom frame and advancing or withdrawing the conveyor mechanism, the discharge point for bulk materials relative to the loading axis can be altered radially and angularly without interrupting the flow of bulk materials through the system. A supply bridge assembly can be employed to bring the bulk materials to the loading axis of the boom.
