While industrial screw conveyors are used mostly in bulk handling
applications, they are popular in agriculture as components of farm machinery like threshers or balers. They also transport animal
feed, grains and seeds to different locations.
The food processing industry also uses industrial screw conveyors to
transport dry ingredients like salt, flour, nuts and any other raw material used to produce food products. These conveyors are always
made from food grade stainless steel, which exhibits a smooth surface and is non-contaminating. They are also popular within the
construction industry when mixing dry and wet materials to form cement or plaster. In some situations, screw conveyors will even
outperform more standard types of conveyor systems.
Screw conveyors fabricated by screw conveyor manufacturers are found in
numerous industrial applications in the agricultural, food and beverage processing, plastic, pharmaceutical, chemical, mining, oil
and gas and construction industries. Because of their gentle handling and blending, screw conveyors can be used to transport a
wide variety of materials in many different industries. Some examples of these products include carbon black, caffeine powder,
gypsum, ferric sulfate, cocoa beans, flour, garlic powder, Epsom salts, vitamins, fiberglass, whey, lead oxide and many other
Because the screw will cut through materials during operation, sticky
substances like gels, materials that do not breakdown easily or
those materials not intended to be broken down are not ideal for screw
conveyor systems to process. Rather, they are used mostly to transport dry to semi-dry bulk materials, both free-flowing and
non-free-flowing.Screw conveyors have three different orientations: horizontal, vertical and inclined. Horizontal screw conveyors
transport the material in a linear direction and require only atrough.
Vertical conveyors carry material straight up and down and require
a tubular casing to hold all the material inside. They are needed when material must be transported from a receptacle low
to the ground to one that is very tall.
Compared to bucket elevators, vertical screw conveyors are lower maintenance and
provide continuous conveying. Finally, many applications require
the use of inclined conveyors, which are set at an angle. They require
ample space and an increased amount of power to lift the material, but their slant economically transports bulk material
between facility floors. Some are portable and mounted on stands, carts or vehicles and may be moved around a facility. Flexible
screw conveyors are able to adjust their angle and may bend in different directions, creating a wider range of uses within a
single facility. Most conveyors, however, are manufactured out of steel and are therefore unable to move.These conveyors transport
loose, dry materials to and from vats, hoppers, silos, rail cars, barrels, trucks and pits. They can be powered by an electric motor,
although some harness the energy from nearby machinery like a trailer’s power take-off shaft. Standard industrial screw conveyors
are usually constructed with metal. However, some that are used in the food industry are made out of thermoplastic resin that
has been injection molded and can withstand high impact and temperature without contaminating the products they carry. The
selection of screw conveyors depends upon the industrial application, material and material consistency as well as
additional operations required of the screw conveyors system.
