Conditions for which back flow will be initiated in vertical screw conveyors conveying cohesionless granular material are theoretically established. Use is made of existing knowledge of the performance characteristics of such conveyors. Provided the conveyor is operated at not too low an angular speed, no back flow occurs for granular agricultural products. Experimental confirmation has been obtained in conveying 5 different kinds of agricultural seeds.
