Superior s conveyor calculator provides the minimum horsepower required at the headshaft of a conveyor

A screw in the horizontal is a conveyor or feeder but as a screw is inclined it very quickly becomes a lift or pump All of the charts amp formulas for calculating speed and capacity for a screw in the horizontal are no longer applicable what now comes into play is product knowledge and experience for sizing and calculating speed and horse power for incline and vertical screws

horizontal screw conveyors too but so far these efforts have failed to produce an applicable design method for this appliion the horizontal highcapacity screw conveyor A further problem lies in calculating the power rating for vertical conveyors as used for example in the continuous unloading of bulk carriers The institute also

Calculation of the nominal flow can be done once the screw geometry its rotation speed and the filling coefficient are known The flow rate of a screw conveyor or feeder depends on a number of interlinked factors geometry of the screw rotation speed inclination geometry of the feed hopper and tube flowability of the material
