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. As the degree of incline increases, conveying efficiency is reduced and horsepower requirements increase due to the effects of gravity and bulk material fall back.
For screw conveyor design purposes, conveyed materials are classified in accordance with the code system shown in Table A. This system conforms to that of the Conveyor Equipment Manufacturers Association (CEMA) which ranks each material in 5 categories. Table B lists the codes for many materials that can be effectively conveyed by a screw conveyor.

Screw Conveyors are versatile and can be employed in horizontal, inclined and vertical installations as well as multiple screw Live Bottom Feeders. Screw Conveyors can be sealed for dust free and vapor tight requirements. A Screw Conveyor can be used for heating and cooling products by utilizing jacketed housings and/or hollow flight screws.
some cases vertical screw conveyors are also used for the transport of screenings and sludge. In conventional design the material is collected into the inlet hopper and is transported by a rotating screw that is situated into a trough with protective lining and lid cover. Discharge of solids is through and end shoot. Drive gear

flight screw shaft, which is a fabricated weldment. The key to proper screw feeder design is to provide an increase in capacity in the feed direction [4]. This is particularly important when the screw is used under a hopper with an elongated outlet. One common way to accomplish this is by using a design …
Aug 12, 2021· Material is fed through the screw conveyor's inlet, passes through the conveyor via the turning auger, and is taken out via the discharge end. Screw conveyors can be configured in a horizontal, vertical, or inclined arrangement. The simplicity of the screw conveyor design allows it to be used in many different applications.
Vertical screw conveyors are an efficient method for elevating a variety of bulk materials from steep inclines to completely vertical. The compact design allows the vertical screw conveyor to fit almost any plant layout. With minimum moving parts, the vertical screw conveyor is a cost-effective and dependable component of any bulk material handling process.
