Magnetic plates
Magnetic plates are used to separate ferromagnetic impurities during transport on a belt conveyor. They are used in waste processing and recycling, product sorting, protection of processing technology, or in areas where permeable materials are transported. They are also increasingly used where manual cleaning of ferromagnetic impurities is no longer feasible. Magnetic plates generate a magnetic field that captures metal particles from the material on the belt.

Key Benefits of Our Magnetic Plates
Strong and consistent magnetic performance
Equipped with high-intensity permanent magnets, our magnetic plates deliver stable, long-lasting magnetic force suitable for fine and coarse contaminants.
Durable stainless-steel housing
Designed to withstand dust, abrasion, impact and heavy-duty industrial environments.
Maintenance-free operation
Magnetic plates have no moving parts and require no electrical power. Cleaning is simple—just wipe captured metal from the plate surface.
Flexible mounting options
Available in a variety of sizes and configurations for mounting above conveyors, across chutes, or inside enclosed process areas.
Custom-built designs
For special applications, we offer bespoke dimensions, bolt patterns, magnetic strengths and construction details.
1Confirm that a plate is the right design for your line
A magnetic plate hangs above a belt conveyor and pulls ferrous contamination out of the material as it passes underneath. It suits waste processing and recycling, product sorting, protection of downstream technology and any line moving permeable material in a layer.
If your material falls through an opening or travels inside a closed pipe, a grid, a hopper magnet or a flow-through separator will do the job better and for a fraction of the price.
2Size the plate to the conveyor, not to the budget
Plates are manufactured in standard sizes according to the conveyor type series, or on request. The stocked sizes run from MD 610x496x227 through 738x583x227 and 835x667x227 to 854x474x210.
The plate has to cover the working width of the belt. A plate narrower than the material stream leaves untreated edges, and on a sorting line that is precisely where larger pieces tend to travel.
3Decide between ferrite and neodymium
Plates are usually fitted with ferrite magnets, which give a deep, stable field that is well suited to catching larger pieces through a thicker layer of material. Where a stronger field is needed, they can be fitted with neodymium magnets instead.
The decision follows from the contamination you are removing: bolts, tools and larger fragments through a deep layer point to ferrite, fine iron in a thin layer points to neodymium.
4Plan the suspension and the working gap
Plates are mounted using four suspension eyes at the corners, so you need a frame or a gantry above the belt and a way to adjust the height. The gap between the plate and the material decides everything: the magnetic force drops steeply with distance, so a plate hung too high looks like a weak plate.
Start close to the maximum layer height and lower the plate in steps until the separation is reliable but the plate is not being struck by the material.
5Work out who clears the captured metal
Standard plates can hold up to 25 kg of captured objects, and cleaning means wiping the metal off the plate surface. There are no moving parts and no power supply, so there is nothing to service, but somebody has to climb up and clear it.
On a heavily contaminated line, work out the interval from how fast the plate fills up in the first week. A full plate stops separating long before anyone notices.
6Ask for a custom build where the standard does not fit
For special applications we supply bespoke dimensions, bolt patterns, magnetic strengths and construction details, including mounting above conveyors, across chutes or inside enclosed process areas. The stainless steel housing is built for dust, abrasion and impact.
Tip: Before enquiring, note three things: the belt width, the maximum height of the material layer and the largest piece of metal you need to catch. Those three numbers decide the plate size, the magnet type and the mounting height, and they turn a rough estimate into a real proposal.

Frequently asked questions about magnetic plates
Standard plates can capture up to 25 kg of objects. That is a capacity figure, not a target: separation stays reliable while the plate has free surface, and falls off as it fills up. On a contaminated line, check how quickly the plate fills during the first week of operation and set the cleaning interval from that.
Using four suspension eyes at the corners of the plate, which means you need a frame or gantry above the belt and ideally an adjustable height. Plates are also mounted across chutes or inside enclosed process areas. Since magnetic force drops steeply with distance, adjustable suspension is worth the extra work at installation.
Plates are usually fitted with ferrite magnets, which produce a deep and stable field suitable for catching larger fragments through a thicker layer of material. Where more strength is needed, the plate can be fitted with neodymium magnets. Larger pieces through a deep layer point to ferrite, fine iron in a thin layer to neodymium.
A plate works above a belt conveyor and pulls contamination up out of a moving layer of material without touching it. A grid is a frame of magnetic rods that the material has to pass through, which suits dry free flowing fractions falling through an opening. Where the material is coarse, mixed or partly sticky, the plate wins because nothing can block it.
No. It has no moving parts and no electrical supply, so there is nothing to wear out or control. Cleaning means wiping the captured metal off the plate surface. The stainless steel housing is designed for dust, abrasion, impact and heavy duty industrial conditions, which is what gives the plate its service life on a recycling or sorting line.
Yes. Plates are made in standard sizes according to the conveyor type series or on request, and for special applications we supply bespoke dimensions, bolt patterns, magnetic strengths and construction details. Send us the belt width, the maximum material layer height and the type of contamination you need to remove, and we will design the plate around them.
On a conveyor line, the metal you do not catch ends up in a crusher, a mill or a customer complaint. Magnetic plates hang above the belt and pull ferrous contamination out of the passing material without touching it, which is why they replace manual picking on recycling and sorting lines. We supply standard sizes from MD 610x496x227 up to 854x474x210, normally with ferrite magnets and optionally with stronger neodymium magnets, in a stainless steel housing built for dust, abrasion and impact, with a capture capacity of up to 25 kg on standard plates. For anything outside the catalogue we build the plate to your dimensions, bolt pattern and magnetic strength.
