A magnetic separator, intended exclusively for industrial use, ensures perfect cleaning of your dry mixtures from ferromagnetic impurities (by ferromagnetic impurities we mean fully magnetic metals such as iron, nickel, cobalt and iron-containing alloys, not paramagnetic, very weakly magnetic materials).
For proper operation, the mixtures being purified (the material you pour through the magnetic separator) must be:
- homogeneous,
- dry and free-flowing, so that the magnetic separator does not become clogged – see further below.
The magnetic separator is suitable for use only in non-continuous operations (during manual cleaning of the magnetic separator, the flow of the purified material must be stopped). It is installed only in vertical pipelines (if vertical installation is not possible, do not use this product and contact us to select another magnetic separator, or to confirm the suitability of its use), e.g. in the food and chemical industries, agriculture, waste-processing industry, and in the production of building materials – see the list of suitable materials below.
The pull-out magnetic separator is used as a pre-stage to protect technology so that metal ferromagnetic impurities do not enter equipment that they could damage, such as knives of mills and crushers, nozzles of regranulation and granulation lines, injection-molding machine nozzles, extrusion presses, press stands, shredding equipment, fine screens, ceramic press stands, glass presses, etc. It can also be used to purify the mixture to the highest possible cleanliness, where the separator is placed at the end of the production process just before packaging and dispatch, so that no contamination by ferromagnetic metal material occurs during subsequent operations in the plant. In this case, immediate sealing of the purified material into closable packaging or other closable containers is assumed. Thanks to the excellently designed magnetic labyrinth consisting of two grates placed above each other, a high capture rate of impurities is achieved (please read the detailed description below of which ferromagnetic metal impurities this magnetic separator can capture).
The grain size (fraction, size) of the purified material may be up to a maximum diameter of 5 mm (5x5x5 mm), of regular shape; the material must be free-flowing, dry, non-sticky and free of lumps, so that the magnetic grates are not overloaded (clogged) by the material. By a free-flowing material, as used in this description, we mean a material that, when freely poured, does not tend to bridge (clump into solid masses), does not self-retain and thus does not prevent free flow through the magnetic grates (through the magnetic separator). Examples of such materials (which do not flow well) may include wet or greasy materials, but also materials that at first glance appear dry and seemingly free-flowing, yet their natural property is that they do not flow well. Such a representative is, for example, smooth, very finely milled flour or various very finely milled starches. The materials we recommend, and which in our professional opinion and experience are suitable for pouring (purifying) through this magnetic separator, are listed below (please note the maximum permissible fraction/grain size stated above). If the material from which you require separation of metal ferromagnetic impurities (material to be purified) is not found in the list below, do not use this product and contact us for further clarification and possible recommendation of another magnetic separator, or for confirmation that this type is also suitable for magnetic separation from your material.
Examples of materials suitable for magnetic separation using this magnetic separator:
- bulgur
- powdered mashed potatoes
- powdered potato dumplings
- cereals, various types
- granulated sugar
- powdered sugar (beware of overloading with material; we recommend pouring more slowly and distributing evenly over the entire surface of the magnetic separator)

- malt (beware of abrasion; check protective tubes more often)
- sunflower seeds (finely ground, not whole)
- bread-mix blends
- soy
- building materials (only free-flowing and non-abrasive, without glass and ceramic admixtures)
- breadcrumbs

- dried onion
- dried chocolate
- dried whey
- dried herbs
- dried spices (finely ground or very finely crushed)
- powdered milk

- tapioca pearls
- dough mixes (powdered)
- hulled pumpkin seeds
- vanilla sugar
We again emphasize that materials must be dry, free-flowing (must not tend to bridge), non-abrasive, with a maximum regular granulometry of up to 5 mm in diameter (5x5x5 mm). Throughput capacity varies depending on the material from which you require separation of ferromagnetic impurities; it cannot be determined unequivocally and differs for each type of material. If you are not sure about permeability/throughput capacity, do not use this magnetic separator and contact our commercial-technical department to recommend another type of magnetic separator or to approve the use of this type.
Please note that the wall thickness of the protective tube is very small in order to achieve high magnetic induction (magnetic force) and pull-off force on its surface. Therefore, please also consider the height from which you will pour the material onto the magnetic separator (onto the magnetic grates) (impact height). The height from which the material is poured onto the magnetic grates must not exceed 1 m. This is, however, individual for each type of material. It is not possible to determine and prescribe exactly from what height which material should be poured. Pouring from a great height may cause bending or puncturing of the protective tubes and damage to the entire product. If the height from which your material will be poured onto the magnetic grates is higher than 1 m, do not use this product and contact our commercial-technical department to recommend another type of magnetic separator or to approve the use of this type.
This magnetic separator captures (separates) magnetic metal particles from a size of 1 µm and smaller (ferromagnetic in nature, immeasurable, magnetic dust) up to a size of approx. 5 mm (5x5x5 mm), which is the maximum fraction (size) of material that may fall onto the magnetic separator and that may be poured through the magnetic separator. In rare cases, the magnetic separator can also capture larger metal objects up to a size of approx. 10 mm (10x10x10 mm). However, a random occurrence of these impurities is assumed at max. up to 1% of the total hourly throughput capacity of the poured material (regular cleaning of the magnetic separator from ferromagnetic impurities is assumed; this does not mean that the entire 1% of larger ferromagnetic impurities may remain on the magnetic tubes for the entire time of pouring the hourly capacity of the poured material). The content of these larger ferromagnetic impurities must not be higher. If the occurrence of these larger ferromagnetic impurities in your material is higher, do not use this magnetic separator and contact our technical-commercial department for professional advice. Larger objects than stated (max. diameter 5 mm, 5x5x5 mm) must not fall into the magnetic separator (onto the magnetic grates), except for the ferromagnetic impurities described above in a random amount. If you are concerned about the presence of even larger ferromagnetic or other impurities/admixtures, it is necessary to install a screen with a mesh size of max. 5 mm upstream so that these larger unwanted objects are captured before entering the magnetic separator (after installing the screen, it is necessary to consider reducing the capacity load/throughput of the magnetic separator). The screen is not part of the magnetic separator delivery. We also point out the possibility that your material may contain a large amount of fine metal impurities (very fine magnetic metal dust smaller than 1 µm), which can coat the magnetic tubes and make the magnetic separator non-passable (fine magnetic particles also pick up the poured material and overload the entire system). At the same time, the magnetic force/efficiency of the magnetic separator will be greatly reduced. If the magnetic tubes immediately after starting the material flow through the magnetic separator become coated and completely “hidden” in iron dust, this is not a defect of the magnetic separator; it is necessary to strengthen magnetic separation with an additional magnetic separator or clean the magnetic grates more often – your material probably contains a very large amount of ferromagnetic particles.
If you are not able to ensure:
- the absence of particles larger in your material than 5 mm (5x5x5 mm)
- a quantity of less than 1% of larger ferromagnetic particles (up to 10 mm) in the hourly capacity
- minimal occurrence of fine metal dust in your material
do not use this magnetic separator and contact our commercial-technical department to recommend another type of magnetic separator or to approve the use of this type.
The magnetic grates in the magnetic separator are designed to capture as many magnetic metal impurities as possible. However, everything depends on the amount of these magnetic impurities present in your material. It is not possible to bindingly guarantee the capture of all ferromagnetic impurities. It is always necessary to consider the specific technology and capacities. If necessary, other types of magnetic separation must be installed upstream or added. Please do not rely solely on this one magnetic separator. If you are not sure, do not use this type of magnetic separator and contact our magnetic separation experts at any time.
Do not use the magnetic separator to separate stainless steel (commonly referred to as “stainless”), even if it appears magnetic/paramagnetic (this can be the case, for example, after passing through various crushers or other forms of deformation; such paramagnetic stainless steels may also be used to manufacture various screens).
The magnetic separator is not intended for magnetic separation of non-ferrous non-magnetic metals, nor for magnetic separation of parts or their portions that contain ferromagnetic metals (e.g., plastic parts with pressed-in remnants of metal parts, crushed window frames with remnants of metal strips, wood pellets with pressed-in fine wires…). If you need to separate (remove) such ferromagnetic impurities as well, do not use this magnetic separator and contact our magnetic separation experts, who will advise you which other magnetic separator to use or what type to add to your separation system.
Please note that during cleaning of the magnetic separator (cleaning the magnetic tubes) it is not possible to use pressurized water. The protective tubes and magnetic cores may be rinsed with freely flowing water. In this case, dry them thoroughly before reuse. A dry cloth may also be used for cleaning, or well-dried compressed air may be used to blow off residual metal impurities and separated material.
Be very careful when cleaning the magnetic separator; the magnetic grates and magnetic cores are very strong after removal, and their attachment to metal objects may cause injury by pinching or sudden clamping. Do not place them on anything magnetic (tables, workbenches, stair stringers, floors…). Also beware of individual components of the magnetic separator snapping together during cleaning.
This magnetic separator is not intended for use in any environment classified as an explosive atmosphere (ATEX).
The magnetic separator is intended for indoor use only. Do not install outdoors.
Magnetic induction measurement procedure
The measurement is performed using a standard gaussmeter with a probe thickness of 0.75 mm at the location with the highest magnetic induction by design – at the pole pieces, or at the lowest point of the arc of the magnetic circuit. The test is repeated 3 times, each time at a different location of the magnetic circuit, and the average magnetic induction is calculated.
Pull-off force measurement procedure
We measure using a polished steel reference standard with a diameter of 10 mm and a height of 20 mm. The measurement is performed at the location with the highest pull-off force by design – at the pole pieces, or at the lowest point of the arc of the magnetic circuit. We record the force at which the standard detached. The test is repeated 3 times and the average pull-off force is calculated.
For your information: 10 N = approx. 1 kg.
As confirmation of the measurement and a guarantee of the measured values, we issue a certificate, and part of the delivery of each magnetic separator is the original measurement report issued specifically for your particular magnetic separator (the report includes the stock and production number).
WARNING:
The resulting pull-off force and magnetic induction depend on many factors – e.g., the dimensions of the reference standard, the air gap between the standard and the tested magnetic circuit, the thickness of the measuring probe, surface contamination, surface finish of the standard, etc. The stated pull-off force and magnetic induction values were measured under ideal conditions of the test environment. However, these values may change depending on the specific type of environment; for example, operating conditions and subsequent wear may affect product efficiency and measurement results. Therefore, the stated values must be considered indicative, and any deviations cannot be considered a defect within the meaning of Sections 2095 and 2161(1)(a) of the Civil Code. To determine the exact value of magnetic induction and pull-off force in a specific case, your own measurement is required. If the measured pull-off force values are not sufficient for you because they do not correspond to the stated values, you can use the guaranteed option to return the goods within 30 days under the conditions stated here: https://magnetickeseparatory.cz/vraceni-zbozi/ and purchase another type of magnetic separator. These 30 days are intended for testing the goods; after this period, the seller may refuse to accept the return.
