A conveying apparatus 10 for transferring material from a feeding station 12 to a series of discharge stations 14 is composed of a feed passageway 18 and a return passageway 20. Located in the passageways 18, 20 is an endless chain 28 carrying a plurality of scrapers 30 for urging the material around the passageways. Bypass channels 22, 24 are located between the opposed end of the feed passageway 18 and return passageway 20 to provide for recycling of material. The essence of the conveying apparatus is that material fed from the feeding station 12 which is not discharged through the discharge stations 14 falls through the bypass channel 22 into the return passageway 20 where it is conveyed to the bypass channel 24 where it rejoins the feed passageway 18.
