Enter three known dimensions into a calculator below to calculate the unknown dimensions (enter dimensions in inches, angles in degrees). Results are rounded to the nearest inch or degree.
Jan 09, 2008 Screw conveyors can be used to convey bulk materials at an inclined angle, but several areas of design should be examined first. Because of the incline of the screw, several conveying problems begin to occur. 1. The horsepower per unit of material increases 2. The efficiency of moving the material forward decreases.
Feb 21, 2017 Most CEMA approved screw conveyor manufacturers have a lab for testing bulk materials at various degrees of incline and can recommend the proper design and construction features. The test information, for bulk materials that have been successfully conveyed in inclined screw conveyors, is typically kept in a database for use on future projects.
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.
Jul 14, 2014 In inclined screw conveyor, as we increase the angle of conveyor from ground, its capacity decreases. Here inclination factor comes in play. Say, if angle of inclination is 15%, inclination factor is 0.75. It means, conveyor capacity will be 0.75times of horizontal conveyor capacity.

Shaftless screw conveyor capacity is calculated using the spiral diameter, spiral pitch, trough loading percentage, degree of incline (if any) and spiral rotational speed. The required speed is then calculated by dividing the required material flow rate by the capacity per revolution.

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 All of the charts & formulas for calculating speed and capacity for a screw, in the horizontal are no longer applicable, what now comes into play is product knowledge and experience for sizing and calculating speed and horse power for incline and vertical screws.
