Used Screw conveyors

About second-hand Screw conveyors

Screw conveyors are known by various names: worm screw, elevating screw, transport screw, water screw, elevating auger, or simply screw. Whichever term you use, screw conveyors are a variant of Archimedes' Screw, an invention by the Greek engineer Archimedes. This invention was originally used primarily for raising water, slurries, and liquids, but nowadays it is employed for transporting various bulk products such as coffee beans, grain, animal feed, fertilizer, soil, or bark. They are also widely used in the food industry and waste processing. Whatever you want to transport, there is a suitable screw conveyor available.

Due to their versatile applications, screw conveyors are widely used in businesses in the agriculture and horticulture sector. Due to the high demand for these conveyor systems, Duijndam Machines is constantly searching for high-quality, second-hand screw conveyors to provide you with a suitable transport solution at a competitive rate.

Second-hand screw conveyors often have many years of life left, and due to the simplicity of their design, they are often easy to repair in case of any future defects. By opting for used screw conveyors, you can significantly save on initial purchase costs and thereby reduce the payback period considerably.

How does a screw conveyor work?

Screw conveyors come in many different shapes and sizes, but their operation is always the same: a spiral inside a (closed) tube rotates. The rotating motion pushes the product, such as grain, from bottom to top. The screw is powered by an electric motor.

The "original" screw is intended for lifting water and is still used, for example, in pumping stations. However, screw conveyors can transport almost all bulk goods. The density of the product to be moved determines the shape and structure of the screw. Take this into account when making a purchase.

Screw conveyors for bulk products

Screw conveyors are widely used for moving bulk goods such as coffee beans, grain, animal feed, fertilizer, soil, bark, and other granular products. Because the screw rotates in a closed tube, there is no spillage, unlike, for example, conveyor belts. This is especially useful for small granular products like grain. In addition, screw conveyors can lift a product with a steep incline due to the closed tube.

Screw conveyors for waste disposal

Screw conveyors also play a significant role in waste processing. At the beginning of these conveyors, there is a funnel-shaped opening, allowing waste to be manually or automatically introduced at the end of, for example, a processing line.

Since screw conveyors are available in all shapes and sizes, such as L-shaped, straight, long, or short, there is always a screw conveyor that fits precisely into your existing processing line or requirement.

Lifting products with screw conveyor systems

Finally, screw conveyors can be used to effectively lift products. On an open conveyor belt without grip, the incline at which products can be lifted is limited. Because an elevating screw rotates in a closed tube, it can achieve a much steeper incline. Therefore, screw conveyor systems are very suitable for lifting products in spaces where the height difference to be overcome is significant in proportion to the size of the space.
