Screw Conveyors

For your valuable goods

Screw Conveyors for bulk material

Screw Conveyors from AMF-Bruns allow gentle transport of your bulk material in any desired direction – whether horizontally, vertically or on inclines. Volume flows of up to 1,400 m3/h and conveying lengths of up to 60 meters per unit can be realized.

Whether dusty, granular or semi-moist bulk material: our screw conveyors are extremely robust and withstand the toughest requirements even in continuous operation. And they do so with minimal space requirements, maximum efficiency and minimal maintenance. Screw conveyors from AMF-Bruns are available in many designs for different applications – also gas- and pressure-tight on request.

For the transportation of e.g. grain, wood chips, pellets, sugar or granulates.

Product variations:

Up high

Vertical Conveyor

When it comes to conveying bulk material in a vertical direction, this system is the right solution. It is designed for transport distances of over 20 meters and is characterized by a good transition from horizontal to vertical conveying. Volumetric flows of up to 1,400 m³/h are proof of the system’s high performance.

High performance – low space requirement: The vertical screw conveyor is ideal for transporting dust, granulate, powder, sludge and problematic goods. Quality features include absolute dust-tightness and impact resistance. In addition, the system can also be made gas-tight at the customer’s request.

Good mix

Moistening Screw Conveyor

Always the right mix: this system is designed for moistening, mixing and conveying dry goods. A twin-shaft version with combing and self-cleaning features is also available – the ideal solution for goods that tend to stick.

Our all-rounder

Trough Screw Conveyor

Whether horizontal, inclined or vertical: the trough screw conveyor transports dust, granulate, powder, sludge and problematic goods on inclines of up to 30 degrees. Thanks to its ability to be used in the most diverse areas, it is a real all-rounder!

The advantages of the robust system include its modular design and extreme flexibility. Reversing operation is also possible. The extremely versatile unit is absolutely dustproof, shockproof and can also be made gas-tight on request. The high performance is also impressive: volume flows of up to 1,400 m³/h are achieved.

Over 30° incline

Tubular Screw Conveyor

Here it goes steeply upwards: The tubular screw conveyor is designed for gradients of more than 30 degrees. In addition, it can be optimally used for volumetric dosing of bulk materials. Conveying lengths of up to 45 meters can be realized per unit. Whether dust, granulate, powder, sludge or problematic goods: our system is completely dust-proof, shock-proof and can also be supplied in a gas-tight version.

Benefit from high performance: the tubular screw conveyor from AMF-Bruns moves up to 1,850 m³ per hour. It also impresses with its maximum flexibility. Reversing operation is also possible.

Lots of volume - no dust

Twin Screw Conveyor

Whether wood chips, sawdust, recycling material or pellets: twin screw conveyors enable the dust-free transport of large conveying volumes. Ideal for use in the wood-based materials industry!

AMF-Bruns twin screw conveyors are available in the standard sizes 2 x 315 to 2 x 1,600. Depending on the size, up to 2,500 m3/h can be conveyed. We deliver our twin screw conveyors in trough lengths of up to 12 m without center bearings.

Our systems are characterized by a wide range of possible uses: They can be used as discharge screws in wheel loader bunkers, under chipper systems or after the OSB strander.

Versatile use

Areas of application for our Screw Conveyors

Gentle – safe – strong. Screw conveyors from AMF-Bruns are optimally suited for industrial sugar production, among other things. One of the most important advantages is the high performance with volume flows of up to 2,900 m3/h. In addition, our systems are designed for horizontal, inclined and vertical operation and allow flexible application options.

Our screw conveyors are used in a wide variety of operating areas. They are ideal for the transport of:

  • Washed sugar beet
  • Haulm and curd
  • Wet, pressed or dry chips
  • Wood chips & pellets
  • Filter cake
  • Raw, wet and granulated sugar

Frequently asked questions

Up to what length can Screw Conveyors be designed?

The length depends on various framework conditions such as conveying capacity, conveyed material, arrangement and size. Basically, however, we can say: Without center bearings, we can realize lengths of up to 12 meters. By using center bearings, lengths of up to 60 meters are even possible.

Can Screw Conveyors be arranged in an ascending manner?

Yes, screw conveyors can be arranged at an angle. Here, too, the possibilities depend on parameters such as conveying capacity, material to be conveyed, arrangement and size. Furthermore, the angle can be increased by constructive measures. With vertical screw conveyors it is also possible to transport goods vertically.

What variations are there in screw conveyors?

In addition to classic transport, screw conveyors can also be used for a variety of other applications. Here are a few examples:

  • Double or multiple shaft designs
  • Vertical screw conveyors
  • Dosing screw conveyors
  • Mixing screw conveyors
  • Moistening screw conveyors
  • Dewatering screws
  • Screw heat exchangers
  • Mobile screw conveyors that can be moved and rotated
