Abstract: A multi-stage conveyor system consists essentially of a loading unit for loose material to be conveyed, an elevator unit and a transom unit for conveying the material to a depositing station. When transferring the material from the elevator unit to a delivery branch of a standard belt, abrasive action on the material by throwing the same and the resulting development of dust are avoided. The conveying conditions comprise changing the position of legs defining an opening angle between the elevator unit and the delivery branch. An elevator belt bearing, as receptacles for the material to be conveyed, receptacles such as boxes or chambers passes through the elevator unit and into a terminal branch in a region of changing the direction of belt travel in a bending reach about a central swivel axis. An open side of the chambers on the elevator belt is covered by the standard belt during travel through the elevator unit and the bending reach about the swivel axis.
