Everything About Flex Screw Conveyors

Flexible screw conveyors go by many names: helix conveyors, screw conveyors, spiral conveyors, and auger conveyors, but they’re all critical components of the manufacturing process.

In this article, you’ll learn nearly everything there is to know about flex screw conveyors, including what they’re used for, the materials they’re constructed of, and what types of flex screw conveyors there are. We’ll also talk about the accessories you’ll need and discuss why you should consider us for your flex screw conveyor needs.

Read on for more information!

What Are They Used For?

Flex screw conveyors are used to transport dry materials. They are truly flexible in that they allow you to transport a number of materials over different distances, at multiple angles, and at different rates of speed.

They’re primarily used in a factory to aid the following industries:
● Food
● Plastics and petrochemical
● Animal feed
● Mining and Minerals
● Agriculture

Flex screw conveyors work well with both free-flowing and non-free-flowing materials. They can transport mixed materials without separating them.
Flexible screw conveyors are unlike other conveyor types because they prevent dry materials from:
● Packing
● Caking
● Seizing
● Smearing

The screw and tube from the flex screw conveyor can be routed vertically, horizontally, or at any angle. They’re fully enclosed and dust-free, preventing contamination. From large pellets to sub-
micron powders, flex screw conveyors are capable of transporting them all in a safe,
contamination-free manner.

The rotating screw can deliver dry materials both upstream and downstream. Keep in mind that as the incline increases, the capacity will decrease. You will likely want to increase the delivery speed to ensure that the materials are transported properly.
Flex screw conveyors can come in a number of configurations, including mobile and custom configurations. This versatility reduces the need for multiple stationary units.

What Are They Made From?

Flex screw conveyors are made from mild steel or stainless steel, with a UHMW Tube Casing. Each has an auger inside which propels the dry materials through the tube. Depending on your needs, the auger may be round or flat.

Every flex screw conveyor consists of the following:
● Inlet
● Discharge outlet/head
● Flexible shaftless auger
● Feed tube casing
● Gearbox
● Motor

The inlet is designed to be easily and quickly disconnected so the flexible screw conveyor can
be effortlessly cleaned just by reversing the screw. An inspection door and discharge spigot also let you ensure the discharge head remains free of build-up.

What Types of These Conveyors Are There?

We offer three different sizes of Flexi Screw Shaft-less screw conveyors for your business. You can choose from 2-inch, 3-inch, or 4.5-inch Mild Steel or Stainless Steel conveyors for your

Here’s a bit more information on the features that come standard with our conveyors:
● Continuous shaft-less auger flights
● Compression-type couplings
● Helical in-line direct drive gearbox
● C-face motors
As we mentioned, your flex screw conveyor can be built with two different kinds of spirals: round and flat. Round spirals are strongest and the most flexible, while flat spirals are your go-to for applications needing higher throughputs. At Carolina Conveying, we can set you up with both!

What is Used With Flex Screw Conveyors?

As helpful as flex screw conveyors are, there’s much more to manufacturing and conveying than the method of transport. That’s why we also offer everything you need to introduce your materials into the flexible screw conveyor, including inlet hoppers with support legs, bag dump
stations, and bulk bag discharge stations to go with your flexible screw conveyor.

We’ve Got the Flex Screw Conveyors You Need

At Carolina Conveying, we’re proud to provide the tools you need for your industry. Our flex screw conveyors will accommodate any C Flange motor (standard, flameproof, chemical duty and more!) and unlike our competitors, our devices use spur gears, which have significantly higher efficiency transmission than worm types.
Need your flex screw conveyor customized? We offer variations to the standard fixed blade beveled edges and closed type. We understand how specific these selections can be, which is why we also provide testing on-site at our Canton, NC facility to ensure you get the proper
selection and rates.
