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.
Screw Conveyors are performing their assigned tasks in virtually all types of industries and, in addition, special designs are being developed for use as components in ... After size is determined 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.
The NORD Screw Conveyor Package offers a compact and cost effective alternative to traditional screw conveyor drives.Closely stepped speed reduction ratios combined with a directly coupled gearmotor or NEMA C-face input design eliminates the need for top motor mounts, pulleys, belts or guards.
The bulk material moves forward with each revolution of the screw. Conveying capacities up to 10,000 cubic feet per hour can easily be handled with Kase Screw Conveyors. Screw Conveyors are ideal for conveying both free-flowing and sticky materials of similar particle size.

Sep 09, 2016· Formula for Screw conveyor horsepower calculation. Screw conveyor flight. Flight calculations are determined using the screw pitch, length, and shaft diameter. Screw conveyor flights are made to be either " helicoid " or "sectional". Helicoid flights are made from a flat bar strip that is wound into a continuous helix.
A larger screw conveyor diameter will be required for lower screw conveyor speeds. Maximum lump size must also be considered when designing a screw conveyor. Please refer to the Bulk Material Lump Size section for further information. The Capacity Table is only intended for designing control fed screw conveyors.

Screw conveyor coupling bolts are used to connect the screw conveyor shaft to the screw conveyor screw. The coupling bolts are specially designed to transmit the rotational movement of the motor to the screw. The coupling bolts shown in the store are stock and available for immediate shipment. Coupling bolts are sorted primarily by screw conveyor shaft diameter.
This paper provides to design the conveyor system used for which includes belt speed, belt width, motor selection, belt specification, shaft diameter, pulley, gear box selection, with the help of standard model calculation. 1.

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.
As a specialist in the field of conveyor technology, Bechtel can also help you with design questions of screw conveyors.
