Q: Can I use the calculator for vertical screw conveyors? A: Yes, the calculator considers the screw conveyor inclination, making it suitable for both horizontal and vertical conveyors. Conclusion. The Screw Conveyor Flow Rate Calculator offers a convenient and accurate solution for professionals involved in material handling systems.
Conveyor length is approximately half of the total belt length. g = Acceleration due to gravity = 9.81 m/sec 2. mi = Load due to the idlers in Kg/m. = Load due to belt in Kg/m. mm = Load due to the conveyed materials in Kg/m. δ = Inclination angle of the conveyor in Degree. H = vertical height of the conveyor in meters.
Typical Conveyor Capacity. 1 in = 25.4 mm; 1 ft 3 /h = 0.028 m 3 /h ; 1 ft/min = 5.08 x 10-3 m/s; The product cross sectional area is defined by the idler trough shape and the product pile on top of the idler trough the trapezoid shape.

S = Screw Conveyor Speed. The torque rating of the drive shaft, coupling shafts, coupling bolts and conveyor screw must be greater than Full Motor Torque for proper design. A 12-inch diameter screw conveyor was selected for the example. The minimum standard shaft size for a 12-inch diameter screw conveyor is 2-inch diameter.
I have several screw conveyors in my plant all running at different speeds. I need to increase the speed of a screw conveyor due to increased capacity. All my drive units are Dodge TA II shaft-mounted gear …
Vertical conveying by Screw Conveyor, on the other hand, is quite successful and it remains that a 45° incline or angles approaching this figure, are the most difficult on which to achieve successful conveying. Additional power is needed to convey on an incline. This added power is a function of the power required to lift the material.
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 is defined as the power required to safely and feasibly convey a bulk material a fixed distance in a screw conveyor. The horsepower required to drive a screw conveyor is called Total Shaft Horsepower, or TSHP. TSHP is a function of the characteristics of the bulk material being conveyed and the friction inherent in the screw conveyor.
