Screw Conveyor Horsepower | Engineering Guide
Using the previous example, a screw conveyor is required to transport 10 tons per hour of unslaked lime with a bulk density of 60 lbs. per cubic foot. The unslaked lime also needs to be mixed in transit using cut and folded flights. The conveying distance is 15-feet so short (2/3) pitch screws will be used to ensure proper mixing.
