Designing Inclined Screw Conveyors for Industrial Applications
Two types of troughs are typically used with inclined screw conveyors: U-trough and tubular housing. The U-trough design is simple, economical, and provides access for maintenance. U-troughs are used in most horizontal screw conveyor applications and inclined applications up to about 20 degrees.Design Screw Conveyor Design Procedure STEP 1 Establish Known Factors 1 .

Screw conveyors can be used, as can bailing, gas-blowing, and vibro-conveyors, but all have issues related to some combination of complexity, inclination, differential friction, and torque reaction.Inclined screw conveyor efficiency may also be detrimentally affected by the geometry of a standard U‐trough. A U‐trough design contains void space over the rotating screw, resulting in material fallback during operation. When performing a standard horizontal screw calculation, consider adding rpm to theInclined Screw Conveyors cemanet

Cylindrical rollers are generally used but designs consisting of series of skate wheels mounted on a shaft or axle are also applied, Figure 2 c). a) b) c) Figure 2. Roller conveyor sections design. 2. CalculationAll 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.

Vertical screw conveyors are a very efficient method for elevating a variety of bulk materials at very steep inclines or completely vertical. KWS considers any screw conveyor located on an incline over 45-degrees to be a vertical screw conveyor. The compact design allows for the vertical screw conveyor to fit into almost any plant layout.
