Inclined Screw Conveyors Inclined screw conveyors typically operate from slightly above the horizontal position to 45 degrees from the horizontal position. Above 45 degrees an inclined screw conveyor is considered a vertical screw conveyor and must be designed in accordance with the CEMA guidelines for vertical screw conveyors.
Inclined screw conveyors are used in thousands of applications and provide a simple solution for conveying and elevating bulk materials. If you utilize inclined screw conveyors in your plant, proper design is very important to the long-term success of your operation.
Jan 09, 2008 Calculate Horsepower For Inclined Screw Conveyors 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.

More horsepower is required for Inclined Screw Conveyors: This is due to both lifting the product and “reconveying” product that falls back. Hangers should be eliminated: They create a “dead flow” area that is emphasized with inclined conveyors. This often results in the use of longer screws which require their own design considerations.

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.
Calculation of Conveyor Speed. Conveyor Speed can be most conveniently calculated, by use of the nomographs supplied on pages. To use this nomograph first locate the two known values (screw diameter, and required capacity, in cu. ft. per hour), then with a straight edge connect these two points.

Sep 09, 2016 Screw Conveyor design calculations. Capacity. The capacity of a screw conveyor is given in cubic feet per hour (ft3/hr.) at one revolution per minute. The capacities of various sizes of screw conveyors, under five cross-sectional loadings, are available in manufacturers manuals. Design of inclined screw conveyor.
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.

89 Belt Tension Calculations W b =weight of belt in pounds per foot of belt length. When the exact weight of the belt is not known, use average estimated belt weight (see Table 6-1) W m =weight of material, lbs per foot of belt length: Three multiplying factors, K t,K x,and K y,are used in calculations of three of the components of the effective belt tension, T
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.
