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.
mined then exact conveyor speed is determined by dividing the required capacity in cubic feet per hour by cubic feet per hour at 1 revolution per minute. Note: If handling a material with hard lumps [lumps that will not break up in the Screw Conveyor] refer below to Table No. 1, "Size of Lumps to Diameter". If the required diameter (as found
If the calculated speed at step 2 is < than the max speed for the screw diameter selected, the design can be kept. If the calculated speed at step 2 is > than the max speed for the screw diameter selected, the design is not suitable and the calculation must be run again by

Note: High starting torque motors must not be used without design verification by Kase’s Engineering Department. Example: A 12-inch carbon steel conveyor has been selected with a required shaft horsepower of 8.9 and a speed of 64 RPM. The drive to be used has an efficiency of 85%, thus requiring a drive input of 10.46 horsepower. Therefore, a 15 horsepower motor must be used.
