Magnetic Length Sorting (MLS)

Sorting by length with the help of magnetism: it's possible!

When it comes to sorting by length, magnetism offers a reliable solution.
The maximum length of the product is the determining factor, regardless of shape, purity, or magnetic force.
Our approach relies on permanent magnetism: highly consistent, energy-efficient, and easily scalable.


Our sorting technique operates through a combination of conveyor belts and magnetism, providing a stable and energy-efficient process. Utilizing permanent magnets ensures simplicity and minimal energy consumption.

Here's how it works:

  1. Product Placement: The product is placed onto a conveyor belt.
  2. Transportation: The conveyor belt transports the product to the magnet zone.
  3. Magnetic Separation: When the product reaches the magnet zone, magnetizable materials (such as iron, steel, nickel, or cobalt) are attracted and placed upright.
  4. Sorting Process: Upon contact with the upper belt, the upright metal is discharged upwards. If there's no contact with the upper belt, the material continues along the conveyor.

Other features / possibilities:

  • Adjustable Separation: The distance between the two belts determines the length at which separation occurs. This distance is infinitely adjustable.
  • Scalability: Our patented technique accommodates parts ranging from 5 mm to 180 mm (and potentially larger) and is fully scalable.
  • Inline Integration: Designed for seamless integration with existing machines, facilitating a continuous process. Standalone operation is also an option.
  • Versatile Design: Simple, robust, and adjustable in length, width, and magnetic force, ensuring adaptability to various production needs.



The initial inspiration behind this technique stemmed from the need to sort high-quality steel wires extracted from car tires by length. Efficient sorting on a large scale, classification, was essential to utilize these fibers effectively as reinforcement in concrete. Presently, no other method offers such precise and cost-effective processing capabilities for this purpose.


With minor adjustments, the technology has proven to be able to serve other markes, for example:

  • Sorting Steel Wire from Car Tires by Length (as described above).
  • Extracting Batteries (such as AA and AAA) from a flow of goods using MLS technology to prevent environmental contamination or melting. The precondition is that these batteries are sufficiently magnetic.
  • Classifying shredded material: MLS technique can extract long iron from shredded material, reducing energy consumption, machine wear, and improving shredded material quality.
  • Replacement of manual sorting.
  • Quality control for production processes.
  • Customized solutions: adaptation of MLS technology to suit specific processes and requirements.
