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.
The design of the screw is based on the theory of the inclined plane. The screw conveyor began to evolve in the late 1800s and was used as a means of increasing food and grain production to meet the needs of the rapidly growing American population. The first feed mills used screw conveyors throughout the .

· Maximum Conveyor Angle of Inclination. This chart consists of triangles representing horizontal, vertical, and inclined distances. Any one unknown distance can be determined when the other two are known. For distances greater than the limits of the chart, divide the given dimensions by a figure to bring within the range of the chart.
calculate inclined screw conveyor textbook requirements for inclined screw conveyors increase with the degree of incline. The Horsepower Factor (Fi) is incorporated into the standard screw conveyor horsepower calculations to compensate for the additional horsepower required to overcome gravity and bulk material fall back. 2 1 0 5 10 15 20 25 30 35 40 45

Books on Materials Handling Conveying. Screw Conveyor 101 by Michael P. Forcade Book Description: A basic training manual for screw conveyors that provides an indepth look at the features, functions, and benefits of most common screw conveyor parts and pieces, as well as thier primary usage, advantages and limitations.
All conveyors require an additional belt tension in order to allow the pulley to drive forward an effective tension without slipping. In a case of a simple horizontal conveyor T1 is the sum of the effective tension Te and the slack side, the tension T2. T 1 = T e + T 2 = For .
INCLINED AND VERTICAL CONVEYINGcan be accomplished with a screw conveyor, however screws lose efficiency rapidly as the incline increases to 45°. Short pitch flights and tubular housings are used to improve efficiency. Conveyor speed must be increased considerably for steeply inclined and vertical screw conveyors.
screw conveyor that's up to the challenge. O ne of the workhorses of dry bulk solids handling, the screw conveyor provides enclosed transfer while moving materials horizontally, vertically, or at an incline. The versatile conveyor's wide range of configurations, components, and construction materials
CONVEYOR POWER CALCULATOR. Use this calculator to calculate the force, torque and power required from a conveyor to move a load at an angle. If your conveyor is horizontal enter an angle of 0.

· the length i am considering for the conveyor is meters. i am considering Regular pitch double type screw conveyor,pedal flight type . i think that smaller pitch will definetely apply more force not only because of the pitch but the resistance of pushing the material will also increase and hence demanding for a higher bkw for the same amount of material to be conveyed .
Thus TSHP is calculated as follows: TSHP = + = Assuming a drive efficiency of 85% resulting in a total drive horsepower of, a standard 2 horsepower motor would be selected for the drive input. The horsepower required for the above conveyor may also be determined graphically by the use of the two horsepower nomographs.

Screw Conveyors are performing their assigned tasks in virtually all types of industries and, in
Inclined and Vertical Screw Conveyors 118 Discussion of capacity versus angle of incline and other factors concerning inclined screw conveyors, including horsepower. Description of vertical screw conveyors, their speeds, capacities, components and horsepowers required.
Screw Conveyors. Screw conveyors are used to convey bulk material from almost any position (vertical, horizontal, or at an incline) and are one of the most reliable methods of conveyance. The screw conveyor is composed of a pipe with a welded steel strip that is formed into a continuous helix. The helix is referred to as the flighting.
inclined screw conveyors typically operate from slightly above the horizontal position to 45degrees from the horizontal position . above 45degrees an inclined screw conveyor is considered a vertical screw conveyor and must be designed in accordance with the kwS Engineering Guide for vertical Screw Conveyors . as the degree of incline ...
Power requirement of Screw Conveyors The driving power of the loaded screw conveyor is given by: P = P H + P N + P st Where, P H = Power necessary for the progress of the material P N = Driving power of the screw conveyor at no load P st = Power requirement for the inclination of the conveyor
