Using a single feeder/conveyor, the discharge height is limited by the maximum allowable deflection of the screw and usually results in a max height of about 8ft for small screw feeders and as high as 15ft for larger screw feeders. 1/2 – 2/3 Pitch For a Inclined Screw Feeder/Conveyor

Determine the size of your Incline Conveyor Get Quote How to use this calculator 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. This should be considered a starting point; contact us for expert assistance.
The flow rate or capacity of a screw conveyor is measured in cubic feet per hour. If the capacity is given in pounds per hour, tons per hour, or bushels per hour, it is converted to cubic feet per hour. Since screw conveyors are …
In inclined screw conveyor, as we increase the angle of conveyor from ground, its …
Motor power: The power requirement of the inclined screw conveyor increases with the increase of the degree of inclination. Additional horsepower is required to overcome gravity and bulk material fall back. Inclined screw conveyor design calculation 1. 10° inclination: At inclinations up to 10°, the loss of conveying efficiency is minimal.
For calculating a screw conveyor (and other bulk conveyors) you can download our free calculation program. Send an e-mail to [email protected] and we will give you the details. You can also do it directly on our website (bulk conveyors ) Good luck with it. Jur Lommerts ================= Jansen & Heuning Bulk Handling Systems The Netherlands

Speed of the screw = horsepower required. Also when estimating horse power the number of starts and stops, the time in-between stops and restarts, and the estimated amount of residual material in the conveyor when starting all must be considered. Inclined Conveyor
The slope of an inclined screw conveyor determines the amount of material it can hold at one time. As the angle increases and becomes steeper, the capacity of the conveyor decreases. For example, a conveyor moving material at 15° can carry 75% of its horizontal capacity, while a conveyor running at 25° can only carry 50% of its horizontal capacity.
The driving power of the loaded screw conveyor is given by: P = PH + PN + Pst Where, P H = Power necessary for the progress of the material P N = Driving power of the screw conveyor at no load Pst = Power requirement for the inclination of the conveyor Power necessary for the progress of the material PH: / Screw Conveyor power calculation

7.1 Design of Screw Diameter for Screw Conveyor: 7.2 RPM of Screw: 7.3 Loading efficiency: 7.4 Inclination Factor: 8 Internal Resources: Design of Screw Conveyor: The size / design of screw conveyor depends on two factors 1. The capacity of the conveyor 2. The lump size of the material to be conveyed (Maximum dimensions of the particle)
Inclined Conveyors: HP= ( (P x B)+ (P+M)x F x S)/33,000 Effective Tension Pull needed to move belt and load horizontally: E= F x (P+M) Tight Side Tension Total tension to move belt and load horizontally: E 2 = E+E 1 Slack Side Tension Additional tension required to prevent slippage on drive pulley: E 1 =E x K Operating Tension

Using the formula below, the exact conveyor speed (S) can be calculated: Nomenclature: S = Conveyor Speed CFH = Capacity in Cubic feet per Hour (ft 3 /hr) 3. Capacity Considerations for Special Pitches Screw conveyor capacity is influenced when the pitch is lowered from standard full pitch. Lowering the auger pitch can hamper the capacity.
correction factor for inclination compared with horizontal conveying (angle written in degrees) = 1 - ( angle of inclination / 50 ) with a minimum of 0,1 (45 degrees) and a maximum of 1,9 (45 degrees down). We calculated a lot of screwconveyors with this formula, but pratice showed that the formula predicts a far lower capacity than real.
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 …
