Metal detection systems for pneumatic conveyance

Metallic contaminants in plastic granulate, regrind, flour or breadcrumbs can lead to blocked nozzles and filters, damaged machines or impure final products. Our metal detectors for pneumatic applications provide optimum protection against interruptions to production and downtime, and against customer complaints.

That's what distinguishes our products

The benefits in detail

  • Thanks to quick-lock couplings and flanges, our metal detectors are extremely easy to integrate into piping systems, regardless of whether they are positioned vertically, horizontally or at an angle.
  • They remove metallic contaminants without interrupting the flow of the conveyed material or reducing the conveying speed.
  • They function reliably, even at high conveying speeds and temperatures.
  • The two-channel technology provides the highest sensitivity to all metals, regardless of whether they are magnetic or not, even when they are embedded in the product.
  • Digital signal processing guarantees optimum security in line with EU directives.
  • Preset operating parameters mean the control units are extremely easy to operate.
  • An exportable, password-protected system logbook or the option of directly connecting to the company network ensures the necessary exchange of data.
  • Our metal detection systems feature an auto-learn function to best compensate for the intrinsic conductivity of the inspected material.
  • ATEX-compliant versions up to zone 20 are available.

Design and alternative configurations

Simple and easy assembly

All components come pre-assembled, and the assembly frame ensures quick and easy installation. A compact design also helps you to save space.

Separation system

Thanks to its responsive shutter flap, the “Quick-Flap” separation unit safely removes metal particles even at high conveying speeds without interrupting the flow of the conveyed material. It also prevents leak air from entering the conveyor pipes. The entire separation mechanics, junctions and separation flap are made out of stainless steel (1.4301).

Different pipe diameters

Integration into already existing conveyor pipe systems with standard nominal widths up to 150 mm is possible without any issue thanks to quick-lock couplings and ventilation flanges.

How artificial intelligence contributes to sustainable and profitable food processing

Despite the breadth of technology available for foreign object detection, certain types of food products remain difficult to inspect via conventional methods. The reason for this is that some foods have high levels of product effect, which can interfere with metal detection. This white paper examines the phenomenon of product effect, the problems it can cause, and why artificial intelligence offers an innovative and promising solution.
