Plate magnetic separator
Plate magnetic separators are robust devices designed to remove ferrous (iron-based) contaminants from powders, granules, bulk solids or free-flowing materials. Installed above conveyors, under chutes or at material discharge/inlet points, they act as a first-line barrier against metal fragments — protecting your production line and improving product purity.

They are used wherever we need to separate impurities originating from iron or steel from other commonly used bulk materials. These include, for example, powdered materials, sawdust, grain, or flour. Thanks to the use of magnetic plates, which allow the material to flow freely, they are ideal for materials with poorer flow properties or for capturing metals that could cause clogging of the grate separator.
Magnetic plate separators are manufactured with inlet diameters of 100, 150, 200, and 250 mm. The body of the magnetic plate separator consists of a welded stainless steel housing, which becomes the main component of the piping system after connection. At the inlet to the separator, there is a deflector roof that directs the flow of material to the magnetic plates, thus helping to achieve maximum efficiency in the separation process. The magnetic housing of the separator is easy to clean and comes standard with ferrite magnets, but can also be fitted with strong neodymium NdFeB magnets on request.
Our Plate Separators – What We Offer
We offer a wide range of plate magnetic separators, designed for different materials, flow conditions, and industrial applications. Options include:
- Standard magnetic plates for coarse or moderately contaminated material flows — ideal where occasional metal contamination occurs.
- High-intensity plates (rare-earth magnets or stronger magnet configurations) — for applications requiring removal of smaller or weakly magnetic particles, or for heavier material streams.
- Custom sizes and configurations — to match conveyor width, chute shape or installation layout. We can adapt plate dimensions, mounting brackets and magnetic strength depending on your needs.
- Easy-mount and easy-clean versions — designed for quick installation and simple maintenance, minimizing production downtime.
1Understand why this design does not clog
Inside the housing, the material flows freely past magnetic plates rather than between rods. That makes the plate separator the right answer for materials with poorer flow properties, and for catching metal pieces that would block a grate separator.
Typical materials are powders, sawdust, grain and flour, plus granules and other bulk solids. If your material flows well and the contamination is fine, a grid captures more for less.
2Pick the inlet diameter from your piping
Plate separators are manufactured with inlet diameters of 100, 150, 200 and 250 mm. The housing is a welded stainless steel body that becomes part of the piping system once connected, so the inlet is not a detail you adjust later with an adapter.
Measure the pipe and check the space available in the run, including the length needed to get the unit in and out for inspection.
3Do not overlook the deflector roof
At the inlet there is a deflector roof that directs the flow of material onto the magnetic plates. It is the part that decides whether the material actually meets the magnetic field or slides past it, and therefore the efficiency of the whole separation.
When comparing designs, ask what happens to the flow inside the housing rather than only how strong the magnets are.
4Choose ferrite as standard, neodymium where needed
The magnetic housing comes as standard with ferrite magnets and can be fitted with strong neodymium NdFeB magnets on request. In the product designations this appears as F for ferrite and N for neodymium versions.
Standard plates suit coarse or moderately contaminated flows where metal appears occasionally. High intensity versions are for smaller or weakly magnetic particles and for heavier material streams.
5Place the unit where it protects something
Plate separators are installed above conveyors, under chutes or at material discharge and inlet points, as a first line barrier before the material reaches the machine you care about.
Putting one at the end of the process tells you how contaminated the material was. Putting one at the intake prevents the damage in the first place, which is where the payback is.
6Specify cleaning and mounting up front
The magnetic housing is designed to be easy to clean, and easy mount and easy clean versions are available for quick installation and minimal downtime. Custom sizes and configurations are also made, including adapted plate dimensions, mounting brackets and magnetic strength.
Tip: Note the inlet diameter, the material and its flow behaviour, the throughput and the largest metal piece you expect. With those four values we can tell you whether a standard MSP 200 or MSP 250 fits, or whether the unit should be configured, before anyone starts modifying piping.

Frequently asked questions about plate magnetic separators
A plate magnetic separator is a complete unit with a welded stainless steel housing that becomes part of the piping system, with magnetic plates and a deflector roof inside. A magnetic plate is a single plate suspended above a belt conveyor by four eyes at its corners. The separator goes into a pipe or chute, the plate hangs over a belt.
Plate separators are manufactured with inlet diameters of 100, 150, 200 and 250 mm. Since the housing becomes a structural part of the piping once connected, the inlet has to match the run from the start rather than being adapted afterwards. Custom sizes and configurations are also available where the standard range does not fit.
Because the magnetic plates allow the material to flow freely instead of passing between rods. That makes the design suitable for materials with poorer flow properties and for capturing metal pieces that could clog a grate separator. For free flowing material with fine contamination, a grid gives more capture surface for the money.
It directs the flow of material onto the magnetic plates, which is what achieves maximum efficiency in the separation process. Without that guidance, part of the stream would pass through the housing without ever coming close enough to the magnetic field, and the unit would appear weaker than it is.
The magnetic housing comes as standard with ferrite magnets and can be fitted with strong neodymium NdFeB magnets on request, which appears as F and N in the product designations. Standard plates suit coarse or moderately contaminated flows, while high intensity versions with rare earth magnets are for smaller or weakly magnetic particles and heavier material streams.
Above conveyors, under chutes or at material discharge and inlet points, as a first line barrier. The rule of thumb is to place it before the equipment you want to protect rather than after it: a separator at the end of the line documents the contamination, one at the intake prevents the damage. Easy mount versions are available for quick installation with minimal downtime.
Plate separators exist for the material that a grid cannot handle: powders, sawdust, grain and flour with poorer flow properties, and metal pieces large enough to block a grate. Inside a welded stainless steel housing that becomes part of your piping system, a deflector roof directs the flow onto the magnetic plates, so the material meets the field instead of sliding past it. Units are made with inlet diameters of 100, 150, 200 and 250 mm, as standard with ferrite magnets and on request with strong neodymium NdFeB magnets for finer or weakly magnetic particles. Plate dimensions, mounting brackets and magnetic strength can all be adapted to your installation.
