5. CONVEYORS9. Bucket conveyorBulk + On-FloorUsed to move bulk materials in a vertical or inclined pathBuckets are attached to a cable, chain, or beltBuckets are automatically unloaded at the end of the conveyor run10. Vibrating conveyorBulk + On-FloorConsists of a trough, bed, or tubeVibrates at a relatively high frequency and smallamplitude in order to convey individual units ofproducts or bulk materialCan be used to convey almost all granular, free-flowing materialsAn Oscillating Conveyor is similar in construction, but vibrates at a lower frequency and largeramplitude (not as gentle) in order to convey larger objects such as hot castings11. Screw conveyorBulk + On-FloorConsists of a tube or U-shapedstationary trough throughwhich a shaft-mounted helixrevolves to push loose material forward in a horizontal or inclined directionOne of the most widely used conveyors in the processing industry, with many applications inagricultural and chemical processingStraight-tube screw conveyor sometimes referred to as an “auger feed”Water screw developed circa 250 BC by Archimedes12.
