At the Wrights Dowson group, we have a long-standing history of creating screw conveyors to our customers’ specifications to serve a wide range of industries and applications. Screw conveyors are innovative but simple machines that move material from one part of a plant to another at a steady pace. This helps streamline various workflows and can help create a safer, more automated work environment.
When it comes to making the most of a screw conveyor, it’s vital to familiarise yourself with the specifications you’ll need. Centreless Screw conveyors come in useful with a variety of products. But what is a centreless screw conveyor, and when should you choose one for your applications?
What’s a Centreless Screw Conveyor, and How Do They Operate?
A centreless screw conveyor is much like any other type of screw conveyor. It conveys materials via a screw in a wear-resistant U-trough. This functions at various angles and even, with the right design, vertically. Materials can also be conveyed across various distances and have one or more exit points.
What makes a centreless screw conveyor special is that it doesn’t have a shaft running through the centre of the screw.
Centreless Screw Conveyors come with heavy-duty construction and can be designed with full enclosures for a dust and contamination-free environment.
The few components make them simple to install even without trained staff present on site. They are also easy to clean and maintain.
When Do You Need a Centreless Screw Conveyor?
Centreless screw conveyors are vital for products with large and uneven particle sizes. With a screw with a shaft, these parts could get stuck and obstruct operation. A centreless screw allows any material to pass on despite its shape and size.
Examples of products that benefit from this are:
- Wood chips
- Asphalt and gravel
They are also well-suited to free-flowing materials such as ash, chemicals and powders, or those materials that might be wet or sticky. In those cases, the material could otherwise start building upon the shaft; hence a centreless design is preferable. Examples include:
- General waste
