The size of screw conveyor depends on two factors. 1. The capacity of the conveyor. 2. The lump size of the material to be conveyed (Maximum dimensions of the particle) For the transportation and dispensing of bulk materials, screw conveyors are one of the most often used machinery. The size of a screw conveyor must be calculated in numerous projects in order to attain the required capacity.

The actual screw conveyor speed is calculated by dividing the Selection Capacity by the capacity at 1-rpm. 1,873/31.2 = 60-rpm 60-rpm is the correct speed for a 16-inch diameter screw conveyor with cut and folded flights and short pitch for conveying and mixing 333 cubic feet per hour.

The speed of the feeder screw can be determined by dividing the desired capacity in cu. ft. / hr. by the figure found in Capacity Table. For maximum efficiency, feeder screw speeds should be slower than standard screw conveyor speeds and allowances must be made for slippage of the material in the screw.

The ideal operation of a vertical screw conveyor is to have a controlled and uniform volume of material feeding. Uneven feeding and start stop operation may adversely affect the performance of the vertical screw conveyors in terms of speed, capacity and horse power.
