A conveyor having divided material flows for its effective operation. When conveying corns or other grain-shaped materials it is desireable to do this quietly and with a low effect. This has been achieved by the present invention by a conveyor consisting of a housing (30), in which an endless belt (35) with adapted width is arranged so that a portion (43) of the material is conveyed on the upper surface of the lower part of the belt. Dog profiles (36) are transversely fixed to the belt and the profiles are arranged and designed to form an interspace (37) between the belt and the bottom (38) of the housing, in which interspace the remainder of the material supplied to the conveyor is conveyed by the dog profiles. Means (42) is arranged for removal of the material flow (43) on the upper surface of the lower part of the belt and transmit said material to common transport.
