Vertically inclined screw feeders (called vertical screw feeders) are often used to deliver material to mixers, silos, and other process and storage vessels. Such a feeder re-quires more power than a horizontal screw feeder. Since the horsepower calculations we've discussed to this point have all been for horizontal screw feeders, we now need to
Construction Monkey calculator that determines an electrical feeder based on load size as well as other variables. It also calculates the voltage drop and maximum distances of the feeders.

Screw conveyors are one of the most reliable and cost-effective methods for conveying bulk materials. Due to their versatility, screw conveyors can convey a wide variety of bulk materials ranging from dry, free-flowing portland cement to wet, sluggish dewatered biosolids.
Variable Frequency Drive (VFD)Selection For Screw Feeders Screw feeders are designed to operate under flooded conditions with a head load of product on the screw or multiple screws. The unit must be designed to overcome the static condition of the screws and the force exerted by the product head load. The product head load exerts a downward
Remember, motor feeder conductors must be protected against the overcurrent that results from short circuits and ground faults but not those that result from motor overload. When sizing the feeder protection, be sure to include only the motors that are on the same phase. Refer to Fig. 5 for this sample motor feeder protection calculation.
DESIGN AND SIZING OF SCREW FEEDERS By Marco Bortolamasi Johannes Fottner ... for the prediction of the power requirement of feeder screws is the influence of very high filling degrees. This means a dramatically ... of the nominal torque of the motor in screw conveyors, and even lower in screw feeders.
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.
The horsepower used for a shaft mount reducer/motor). Calculation of Power Requirement for Screw Conveyor bulkonline . Dec 13, 2006 Power calculations for screw conveyors are available from CEMA publiions and many web sites of conveyor manufacturers.
Here you will be able to follow the key calculations undertaken by the system builder when determining appropriate screw jacks and a drive motor by calculating the power requirement of the system. The formulae used here are not unique to our system builder and the theory can be applied to all screw jack power calculations.

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.
