Conveyor screws work like enormous screws; the material travels one pitch as the conveyor screw rotates in full revolution. The pitch of the conveyor screw is the axial distance between two flight crests. The conveyor screw stays in its position and does not move axially as it rotates to move the material across its length.
The kwS Screw Conveyor Engineering Guide will provide assistance in the design of a screw conveyor or system, yielding optimum performance and eficiency. primary considerations for the selection of a screw conveyor are: Type and condition of the bulk material to be conveyed including maximum particle size and specific bulk density. …
KWS designs and manufactures two types of ribbon flighting – integral leg and post type. Integral leg ribbon flights are manufactured using the same process as sectional flights and the leg is integral with the ribbon. Post type ribbon flights use round bar posts that are typically located every 90 to 120-degrees around the diameter of the pipe.
Half Pitch, Single Flight. Half pitch, single flight screws have the pitch reduced to 1/2 of the diameter and are commonly used in inclined and vertical screw conveyor applications. 1/2 pitch is also used in some variable pitch screw feeder applications.

The actual screw conveyor speed is calculated by dividing the Selection Capacity by the capacity at. 1-. 1,873/31.2 = 60-rpm. 60-rpm is the correct speed for a 16-inch diameter screw conveyor with cut and folded flights and short pitch for conveying and mixing 333 cubic feet per hour. Capacity Table.
The formula used to calculate the Screw Conveyor Flow Rate is as follows: Q = 60 * π/4 * D^2 * S * N * a * d * C. Where: Q = Flow Rate (m^3/h) D = Diameter of the screw conveyor (m) S = Pitch of the screw conveyor (m) N = RPM (Revolutions per minute) a = Loading ratio (Percentage of screw cross-sectional area filled with material) d = Density ...
Screw conveyors must be fabricated from abrasion resistant alloys. Typical materials of construction are AR235, AR400, AR500, TriBraze or chromium carbide overlay. These materials are harder and tougher than A36 carbon steel for resisting abrasion. The carrying face of the screw may be hardsurfaced with a weld-on hardsurfacing material.
With an outer diameter of 150 mm and a screw thickness of 8 mm, the flat diameter was calculated as 134 mm. This calculation ensures that the auger screw fits properly within the system, enabling smooth material …
