Magnetic rods
Magnetic rods are an effective tool for magnetic separation of material in both bulk and liquid mixtures. They are designed for magnetic grids, offering good magnetic performance using strong neodymium magnets and dimensional flexibility of the resulting separation grid. Magnetic rods consist of a closed stainless steel tube with a permanently embedded magnetic core made of cylindrical neodymium magnets.

Magnetic Rods – High-Performance Solutions for Fine Metal Contaminant Removal
Magnetic rods are used in industrial applications for cleaning dry and liquid materials in small to fine fractions. They are very effective at separating impurities from feed mixtures and containers in which agricultural products or foodstuffs are mixed. They are also used in the construction industry, chemical industry, processing industry, and other fields where material purity is important.
Below you will find our standard range of magnetic rods. Customized magnetic rods can be manufactured on request. The magnetic core is non-removable and enclosed within the rod.
The magnetic rod meets the basic requirements of Regulation (EC) No. 1935/2004 of the European Parliament and of the Council of October 27, 2004, on materials and articles intended to come into contact with food.
The product does not contain any chemicals that are classified by the European Parliament and Council Regulation (EC) as carcinogenic, mutagenic, reprotoxic, persistent, bioaccumulative, toxic, and we confirm that they are not included in the Candidate List (SVHC) in concentrations exceeding 0.1% by weight in accordance with Regulation (EC) No. 1907/2006 of the European Parliament and of the Council of December 18, 2006, concerning the Registration, Evaluation, Authorization and Restriction of Chemicals.
Key Benefits of Our Magnetic Rods
High magnetic strength for fine particle capture
Neodymium magnetic cores ensure excellent performance even with very fine powders and materials that require high-intensity separation.
Durable stainless-steel construction
Designed for long service life, resistance to wear, corrosion and demanding industrial conditions.
Suitable for dry and wet materials
Effective in powder processing, granulated materials and liquid or semi-liquid mixtures.
Easy to clean and maintain
Magnetic rods operate without energy, moving parts or complex controls, and cleaning them is simple and quick.
Custom sizes available
We manufacture standard and custom-length rods to fit your hopper, pipeline, chute, mixing system or manufacturing line.
1Know what you are actually buying
A magnetic rod is a closed stainless steel tube with a permanently embedded core of cylindrical neodymium magnets. The core is not removable, which is exactly what makes the rod hygienic and durable: there is nothing to come loose, nothing to trap material and nothing for an operator to reassemble incorrectly.
Rods are the building block of magnetic grids and separators. You buy them either as spare parts, or to build a separation grid to your own dimensions.
2Take the length from the opening, the diameter from the fraction
Stocked lengths run from 150 mm up to 500 mm in steps of 150, 200, 250, 300, 350 and 500 mm, in diameters of 20, 25 and 26 mm. The length has to match the internal width of the chute, hopper or frame the rod will sit in.
Thicker rods carry a stronger field over a larger surface and suit finer fractions. Thinner rods let you place more of them side by side in the same opening, which matters when spacing between rods decides what gets through.
3Compare the three figures on the label
Every rod states induction, pull force and temperature. In the stocked range that means 14,500 Gs with 95 N at 80 °C on the main NdFeB rods, 13,400 Gs with 96 N at 80 °C on the UP version, and 12,000 Gs with 102 N on the 26 mm rod.
Induction decides how fine a particle the rod pulls out of the stream, pull force tells you how firmly it holds what it has caught. For fine iron dust go by the gauss figure, for larger fragments in a fast flow by the newtons.
4Check the temperature before anything else
The standard rods are rated to 80 °C and a version rated to 120 °C is stocked for warmer processes. Overheating a neodymium core weakens it permanently and the rod will keep looking perfectly fine while separating far less.
Count in short peaks: drying, a hot batch, a summer day in a poorly ventilated hall. If the process sits close to 80 °C, take the 120 °C version.
5Use rods for dry and for wet material
Rods work in dry bulk and in liquid or semi liquid mixtures in small to fine fractions. They are used in feed and food production, including containers where agricultural products or foodstuffs are mixed, and in the construction, chemical and processing industries.
For textile filters there is a dedicated design, the filter bag magnet, available with one or two rods.
6Order a custom length instead of compromising
The stocked sizes are a standard range, not a limit. Rods are manufactured to custom lengths to fit a specific hopper, pipeline, chute, mixing system or production line, which is usually cheaper than rebuilding the equipment around a catalogue size.
Tip: If you are replacing rods in an existing grid, measure the old one rather than reading the drawing, and count how many rods the frame holds. Grids are often retrofitted over the years and the real spacing rarely matches the original documentation.

Frequently asked questions about magnetic rods
Take the length from the internal width of the opening, chute or frame the rod will sit in. Stocked lengths are 150, 200, 250, 300, 350 and 500 mm, in diameters of 20, 25 and 26 mm. A thicker rod carries a stronger field over a larger surface and suits fine fractions, a thinner one lets you fit more rods into the same opening. Custom lengths are manufactured on request.
Gauss is the magnetic induction at the rod surface and decides how fine a particle is pulled out of the flowing material. Newtons state the pull force, in other words how firmly the rod holds what it has captured. The main stocked rods state 14,500 Gs and 95 N, the UP version 13,400 Gs and 96 N, and the 26 mm rod 12,000 Gs with 102 N. For fine iron dust follow the gauss figure, for larger fragments in a fast flow the newtons.
No. The magnetic core is permanently enclosed inside the stainless steel tube and cannot be removed. The rod is cleaned from the outside by wiping the captured iron off the surface. Where cleaning needs to happen in seconds and without touching the material, choose a telescopic grate separator, where the whole rod slides out of the flow.
The magnetic rod meets the basic requirements of Regulation (EC) No 1935/2004 on materials and articles intended to come into contact with food. It also contains no substances on the REACH candidate list (SVHC) above 0.1 percent by weight under Regulation (EC) No 1907/2006. Rods are used in food and feed production, including containers in which foodstuffs are mixed.
Yes. They are designed for the separation of ferrous contamination from both bulk and liquid mixtures in small to fine fractions, which is why they appear in powder handling, granulate lines and liquid or semi liquid media alike. The stainless steel tube resists wear and corrosion, so a wet process does not shorten the service life the way it would with an unprotected magnet.
Yes. Besides the standard range, rods are manufactured to custom lengths to fit a specific hopper, pipeline, chute, mixing system or production line. Send us the length, the required diameter, the working temperature and the material you process, and we will confirm the design and quote it. For textile filters there is a separate design available with one or two rods.
The magnetic rod is the part that does the actual separating, whatever the frame around it looks like. Ours are closed stainless steel tubes with a permanently embedded neodymium core, in lengths from 150 mm to 500 mm and diameters of 20, 25 and 26 mm, with values of up to 14,500 Gs and 95 N and temperature versions for 80 °C and 120 °C. The rod meets the basic requirements of Regulation (EC) No 1935/2004 for materials in contact with food, which matters in feed and food production. Because we manufacture separators ourselves, we can also make rods to a custom length for your hopper, pipeline or mixing system rather than asking you to rebuild the equipment around a catalogue size.
