Some design questions of vertical screw conveyors 5 tional revolution speed may result in the desired conveying velocity and the conveying rate. The diagrams similar to Fig. 2 and 3 can support this difficult course of decision-making. It is noteworthy, that the results do not give a good account of the current design practice.
