Total Shaft H.P. Calculation. TSHP = FHP + MHP* *Corrected if below 5 HP. Note: The actual motor horsepower required to drive the loaded conveyor system is dependent on the method used to reduce the speed the motor to the required speed of the conveyor. Drive losses must be taken into consideration when selecting the motor and drive equipment.
A standard Screw Conveyor inclined 15° upward will carry 75% of its rated horizontal capacity. At an inclination of 25°, a standard conveyor may only handle 50% of its horizontal capacity. These are estimated figures and will vary with the characteristic of the material being handled.
This allows for direct connections and optimizes layout design flexibility. End-to-end and side connections not possible on shafted screw conveyors are common solutions available in the shaftless design. Vertical shaftless conveyors are available in a single unit up to 50 feet and systems in excess of 100 feet in elevation gain.
