Provide an enclosed conveying system, such as a screw conveyor, in place of a chain-drag or open conveyor belt where possible. Totally enclose and exhaust ventilate the conveyor from loading to transfer points. Conveyor Belt Ventilation Diagram; Provide a trough belt and conveyor skirting to minimize spillage.
The "Screw Conveyor Design Procedure" on the following page gives ten step-by-step instructions for properly designing a screw conveyor. These steps, plus the many following tables and formulas throughout the engineering section will enable you to design and detail 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 KWS Engineering Guide for Vertical Screw Conveyors.
Sizing a screw conveyor can be very easy, when you know a few of the basics. Of course, there are many screw conveyor applications which add elements to the calculation set that require some experience and expertise but for most traditional applications the process is well defined and resources are available in every screw conveyor manufacturer's catalog.

9.15.1 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.
Every KWS screw conveyor is designed to this criteria with a minimum safety factor of 5 to 1. The motor on the screw conveyor will stall out before there is a mechanical failure of a screw conveyor component. Maximum torque ratings for each screw conveyor component are shown in …
· A screw conveyor hanger bearing is commonly used in screw conveyors over about 12-14 feet. It is a friction, also called a plain, bearing used to support the coupling shaft and the ends of multiple screws. The bearings are available in a verity of materials, with wood and hard iron being the …

Material Horsepower – A straight edge placed at the first two known values, conveyor capacity and Material Horsepower Factor, will intersect a reference point on the centerline. A straight edge from the reference point to the third known value, conveyor length, will intersect the unknown value, Material Horsepower, on the last line.
While belt conveyors are open and often used to move discrete items, a screw conveyor is often enclosed in a trough and used to transport loose materials from one place to another, including concrete, dry sand, plaster, chalk, or grain. A feed screw is also used for feeding lumpy materials like gravel, limestone, or ice.

A 12-inch diameter screw conveyor was selected for the example. The minimum standard shaft size for a 12-inch diameter screw conveyor is 2-inch diameter. The corresponding pipe size is 2-1/2-inch schedule 40 pipe with 5/8-inch diameter coupling bolts. The materials of construction of the screw conveyor is carbon steel.
Use lifting tab to hoist screw conveyor drive into position. Slide shaft into screw and adapter over trough end studs. Only one set of adapter holes will fit over the trough end studs. If the mounted position of the screw conveyor drive varies more than 15° from any of the four horizontal mounting positions shown in Fig. 3, an incorrect set of ...
The diagram below illustrates flow direction for "right-hand" and "left-hand" conveyors when rotated clockwise or counterclockwise. A right-hand screw conveyor pulls the material toward the end which is being rotated clockwise. The direction of flow is reversed when the direction of rotation is reversed.
