The magnetic separator, designed 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 cleaned mixtures (the material you pour through the magnetic separator) must be:
- homogeneous,
- dry and with good flow properties to prevent clogging of the magnetic separator – 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 cleaned 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 suitability of use), e.g., in the food and chemical industries, agriculture, the 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 technologies so that metal ferromagnetic impurities do not enter equipment they could damage, for example knives of mills and shredders, nozzles of regranulation and granulation lines, injection molding machine nozzles, extrusion lines, pressing lines, shredding equipment, fine screens, ceramic pressing lines, glass presses, etc. It can also be used to clean the mixture to the highest possible purity, where the separator is placed at the end of the production process just before packaging and dispatch to prevent any further contamination by ferromagnetic metal material during subsequent operations in the production plant. In this case, immediate sealing of the cleaned material into sealable packaging or other sealable containers is assumed. Thanks to the excellently engineered magnetic labyrinth, consisting of a pair of grids positioned one above the 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 granularity (fraction, size) of the cleaned material may be a maximum of 5 mm in diameter (5x5x5 mm), of regular shape; the material must be free-flowing, dry, non-sticky and without lumps so that the magnetic grids are not overloaded (clogged) by the material. By “free-flowing material” used in this description, we mean such material which, when freely poured, does not tend to form bridges (clump into solid masses), does not self-retain and thus does not prevent free flow through the magnetic grids (through the magnetic separator). Examples of such materials (that pour poorly) may be wet or greasy materials, but also materials that appear dry and seemingly free-flowing, yet their natural property is poor flow. Such an example is smooth, very finely milled flour or various very finely milled starches. The materials we recommend and which, in our expert opinion and experience, are suitable for pouring (cleaning) through this magnetic separator are listed below (we draw attention to the maximum permissible fraction/granularity stated above). If the material from which you require separation of metal ferromagnetic impurities (material to be cleaned) is not found in the list below, do not use this product and contact us for further specification and possible recommendation of another magnetic separator or confirmation that this type is suitable for magnetic separation from your material.
Examples of materials suitable for magnetic separation using this magnetic separator:

We reiterate that materials must be dry, free-flowing (must not have bridging properties), non-abrasive, with a maximum regular granulometry 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 unambiguously and differs for each type of material. If you are not sure about the throughput/capacity flow, 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 cover 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 grids) (impact height). The height from which the material is poured onto the magnetic grids must not exceed 1 m. This, however, is individual for each type of material. It is not possible to precisely determine and prescribe from what height a given material should be poured. If poured from a great height, the cover tubes may bend or be punctured and the entire product may be damaged. If the height from which your material will be poured onto the magnetic grids 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 1 µm and smaller (ferromagnetic in nature, immeasurable, magnetic dust) up to approx. 5 mm (5x5x5 mm), which is the maximum fraction (size) of material that may fall onto the magnetic separator and be poured through it. In exceptional cases, the magnetic separator can capture even larger metal objects up to approx. 10 mm (10x10x10 mm). However, only accidental occurrence of these impurities is assumed, max. up to 1% of the total hourly 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 can remain on the magnetic tubes throughout pouring the hourly capacity of the 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 expert advice. Larger objects than stated (max. diameter 5 mm, 5x5x5 mm) must not fall into the magnetic separator (onto the magnetic grids), except for the ferromagnetic impurities described above in an accidental amount. If you are concerned about the presence of even larger ferromagnetic or other impurities/additives, it is necessary to install a screen with a mesh size max. 5 mm upstream so that these larger undesirable 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 supply. We also warn of 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 block the magnetic separator (fine magnetic particles also bind 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 become coated after starting the material flow through the magnetic separator and “disappear” into iron dust, this is not a defect of the magnetic separator; it is necessary to strengthen the magnetic separation with another magnetic separator or clean the magnetic grids more often—your material probably contains a very large amount of ferromagnetic particles.
If you are not able to ensure:
- absence of particles larger than 5 mm (5x5x5 mm) in your material
- an amount 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 grids 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, additional types of magnetic separation must be installed upstream or added. Please do not rely solely on this one magnetic separator. If you are unsure, do not use this type of magnetic separator and contact our experts in magnetic separation at any time.
Do not use the magnetic separator to separate stainless steel (commonly referred to as “stainless”), even if it appears magnetic/paramagnetic (such as after passing through various shredders or other forms of deformation; likewise, these paramagnetic stainless steels can 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 components that contain ferromagnetic metals (e.g., plastic parts with embedded remnants of metal pieces, shredded window frames with remnants of metal strips, wood pellets with embedded fine wires…). If you need to separate (remove) such ferromagnetic impurities as well, do not use this magnetic separator and contact our experts in magnetic separation, who will advise which other magnetic separator to use or what type to add to your separation setup.
Please note that during cleaning of the magnetic separator (cleaning of the magnetic tubes), it is not possible to use pressurized water. The cover 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 grids and magnetic cores are very strong after removal, and their attraction to metal objects can cause injury by pinching or forceful snapping. Do not place them on anything magnetic/metal (tables, workbenches, stair stringers, floors…). Also beware of the 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 for indoor use only. Do not install outdoors.
Magnetic induction measurement procedure
The measurement is performed using a standard gaussmeter with a 0.75 mm thick probe at the location with the highest magnetic induction by design—at the pole pieces, or at the lowest point of the magnetic circuit arc. The test is repeated 3 times, each time at a different location on 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 magnetic circuit arc. We record the force at which the reference standard detaches. 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 an original measurement report for each individual magnetic separator delivered (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 reference standard and the tested magnetic circuit, the thickness of the measuring probe, surface contamination, surface finish of the reference standard, etc. The stated pull-off force and magnetic induction values were measured under ideal conditions given by the test environment. However, these values may change depending on the specific type of environment, where, for example, operating conditions and subsequent wear may affect the product’s efficiency and measurement results. The stated values must therefore be considered indicative, and any deviations cannot be considered a defect within the meaning of Section 2095 and Section 2161(1)(a) of the Civil Code. To determine the exact value of magnetic induction and pull-off force in a specific case, it is necessary to perform your own measurement. If the measured pull-off force values are not sufficient for you because they do not correspond to the stated values, you may 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 specifically for testing the goods; after this period expires, the seller may refuse to accept the return.
