Based on MY interpretation of what my little slide rule indicates that if you're moving 10,000 lbs of portland cement per hour in an 20 inch diameter screw that is 45% (max recommended) loaded, the screw speed should be about 100 RPM. If the conveyor is 100 feet long the HP required is about 1.4 HP to move the material.
