For proper operation, the purified loose mixtures (the material you pour over the magnetic rod) must have the following properties:

• Homogeneous
• Dry with good flow properties, non-sticky, so that it does not adhere to and stick to the magnetic rod, see below for the description of suitable materials for magnetic separation using a magnetic rod. 

This rod has a drop shape with a basic diameter of 25 mm. It is fully magnetic even at the tip of the drop. It is used especially for installations where it is necessary that the material does not remain on the top of the tube and thus no material loss occurs. It also helps smooth pouring when installed for materials with poorer flow properties.

If the conditions of use differ, the material properties do not match the description above, and the magnetic particles differ from those described by us, do not use this magnetic rod and contact our technical-sales department to confirm the use of this magnetic rod or to recommend another magnetic separator. 

The magnetic rod is used as a pre-stage for protecting technology so that ferromagnetic impurities do not enter equipment that they could damage, for example knives of mills, crushers, nozzles of regranulation and granulation lines, nozzles of injection molding machines, extrusion presses, pressing machines, presses in wet pressing, shredding equipment, fine sieves, ceramic pressing machines, glass presses, etc. It can also be used for purifying the mixture to the highest possible purity (meaning removal of ferromagnetic admixtures), when the magnetic rod is placed at the end of the production process just before packaging, dispatch, transfer, so that no contamination occurs during further operations in the production plant. In this case, immediate sealing of the purified material into sealable packaging or other sealable containers is assumed. Thanks to the very high magnetic force, there is a high capture rate of ferromagnetic impurities (please read carefully below the description of what sizes of ferromagnetic impurities this magnetic rod captures).

The magnetic rod is primarily intended for creating a magnetic grate according to the customer's needs. It has a thread on one side. Using this thread, you can screw this rod onto any flat steel bar or into another auxiliary structure designed by you. No auxiliary structures or flat steel bars, holders, or connecting material are included in the delivery of the magnetic rod. Due to the very high magnetic force, we point out the necessity of using non-magnetic steel for all materials from which your auxiliary structure or any holder for mounting magnetic rods will be made; likewise, the connecting material must be non-magnetic. The minimum distance between rods after installation on your auxiliary structure, holder, or strip must not be less than 20 mm. This is for safety reasons during installation and also so that the rods do not spontaneously attract each other by magnetic force. Also consider the properties of the material (both loose and liquid) so that the required flow and throughput are maintained. If you design auxiliary holders for magnetic rods yourself, we cannot assume any responsibility for the proper function of the magnetic rods. If you are unsure about the installation or assembly into the form of a magnetic grate, do not buy the magnetic rod and contact our sales-technical department. We point out the very high intensity of the magnetic force. Exercise extreme caution when designing and manufacturing your own assembly for placing multiple magnetic rods next to each other and especially when screwing them together (during any assembly), separate the individual magnetic rods from each other with non-magnetic spacers, e.g. a wooden board. There is an increased risk of injury from the joining of magnetic rods! Keep all magnetic materials, structures, and tools such as hammers, pliers, vises at a minimum distance of 200 mm from the magnetic rods. Also beware of the workbench, which must not be iron (ferromagnetic)!

You can also use the magnetic rod separately by directly and freely inserting it into the material, both into dry material and also into liquid material. It is moisture-resistant, so it can be immersed (partially or even completely) in liquids. Do not insert the magnetic rod or use it in aggressive substances and acids. The pH of the liquid into which you place the rod (where you will use the magnetic rod) must be in the range from a minimum value of 6.5 to a maximum value of 8.5. If the liquid has a different pH, do not use the magnetic rod. Contact our technical-sales department for more information, confirmation of the suitability of using the magnetic rod, or possible recommendation of another product from our range.

The magnetic rod can also be used for magnetic separation from loose mixtures (from dry material). Freely hang it, place it, position it in a place that you determine to be best for the function of this magnetic rod. You can also mount it anywhere using a screw. The screw is not included in the delivery of the magnetic rod. Do not place or hang the rod where any ferromagnetic material is in its immediate vicinity or may occur, as the magnetic rod could attach to this material. There is a risk of injury to the operator and poor function of the magnetic rod (when a metallic magnetic metal acts permanently on the magnetic rod, its force decreases, e.g. if the magnetic rod were installed very close to a ferromagnetic beam or placed in an iron (magnetic) trough). The minimum distance of all magnetic objects from the magnetic rod is 200 mm. If you are not able to ensure a place where the magnetic rod will not be in contact with magnetic objects (iron magnetic beams, hoppers, discharge chutes, troughs, slides, various similar structures), do not use this magnetic rod. Contact our technical-sales department for more information, confirmation of the suitability of using the magnetic rod, or recommendation of another product.

You can therefore use the magnetic rod in an assembly of several magnetic rods or separately, as stated, either for liquids or for dry mixtures. Below we provide examples of materials for which you can use the magnetic rod to separate metallic magnetic impurities (magnetic separation).

Note: all liquid materials must meet the pH requirement from min. 6.5 to max. 8.5, all dry, loose mixtures must comply with the maximum material size stated in this text (diameter 0-3 mm, max. size 3x3x3 mm), and likewise magnetic metals must not exceed the dimensions stated here (diameter 0-3 mm, max. size 3x3x3 mm). If your material has a larger grain size or you expect the occurrence of larger magnetic impurities, do not use this magnetic rod and contact our sales-technical department to recommend a suitable product for your purposes.

We point out that the wall strength (casing) of the magnets, the stainless steel tube, is very small (very thin wall) in order to achieve high magnetic induction (magnetic force) and pull-off force on its surface. Therefore, please also consider the height from which, in the case of using the magnetic rod for loose material, you will pour the material onto the magnetic rod (drop height). In general, the drop height should not exceed 1 m. However, this is individual for each type of material. When pouring from a great height, the stainless steel protective jacket may bend or be punctured and the entire magnetic rod may be damaged. If the height from which your material will be poured onto the magnetic rod is higher than 1 m, do not use this product and contact our sales-technical department to recommend another type of magnetic separator or to approve the use of this type of magnetic rod.

This magnetic rod captures (separates) ferromagnetic particles from a size of 1 µm and smaller (metallic in character, immeasurable, magnetic dust) up to a size of dia. 3 mm (3x3x3 mm), which is the maximum fraction (size) of material that may fall onto the magnetic rod and that may be poured over the magnetic rod. For liquid mixtures, such a large material fraction is not assumed, but in this case it refers to the maximum size of metallic ferromagnetic impurity. No larger objects than those stated by us may fall onto the magnetic rods (no larger objects may flow through the magnetic rods) (max. diameter 3 mm, 3x3x3 mm). If you are concerned about the presence of even larger metallic ferromagnetic or other impurities and admixtures, it is necessary to install a sieve with a mesh size of max. 3 mm upstream so that these larger undesirable objects are captured before coming into contact with the magnetic rod. The sieve is not included in the delivery of the magnetic rod. We also point out the possibility that your material (both dry and liquid) may contain a very large amount of fine metallic impurities (very fine metallic magnetic dust), which may coat the magnetic rods and, in the case of an assembly of multiple magnetic rods next to each other, make this assembly impassable. At the same time, the magnetic force will be greatly reduced, and this also applies to a magnetic rod used separately. If your magnetic rods become immediately coated and completely “hidden” in iron dust, this is not a defect of the magnetic rod, but magnetic separation needs to be strengthened by another magnetic rod or another type of magnetic separator. Likewise, more frequent cleaning of the magnetic rod may be sufficient. 

If you are not able to ensure this (absence of larger particles in your material, very large amount of fine metallic dust in your material), do not use this magnetic rod and contact our sales-technical department to recommend another type of magnetic separator or to approve the use of this type.  

Magnetic rods are designed to capture as many metallic magnetic 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 magnetic 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 only on this one magnetic rod. If you need advice, contact our experts in the field of magnetic separation at any time.

Do not use the magnetic rod for the separation of stainless steel (commonly referred to as stainless), even if it appears magnetic (such materials may occur, for example, after passing through various crushers or after other forms of deformation; likewise they may be used for the manufacture of various sieves). The magnetic rod is not intended either for the separation of non-ferrous non-magnetic metals or for the separation of components or their parts that contain metals (e.g. plastic parts with pressed-in residues of metallic parts, crushed windows with residues of metal strips, wooden pellets with pressed-in fine wires…). If you need to separate (isolate) such metallic magnetic impurities as well, contact our experts in the field of magnetic separation at any time, and they will advise you which other magnetic separator to use or what type to supplement your separation assembly with.

We point out that during cleaning of the magnetic rod, pressurized water may be used only from a maximum distance of 300 mm from the magnetic rod. The magnetic rod may be soaked and rinsed during cleaning (using ordinary water only). You may also use a dry cloth for cleaning or well-dried compressed air to blow off residual metallic impurities and separated material. The use of personal protective equipment is required when manually wiping off metallic magnetic impurities. Be careful when cleaning an assembly of multiple magnetic rods.

This magnetic rod is not intended for use in any environment classified as an explosion hazard environment (ATEX).

Do not use the magnetic rod for any purposes other than those described above.

Procedure for measuring magnetic induction

The measurement is performed using a standard gaussmeter with a probe thickness of 0.75 mm at the point with the structurally highest magnetic induction - at the pole extensions, or at the lowest point of the arc of the magnetic circuit. We repeat the test 3 times, each time at a different point of the magnetic circuit, and calculate the average magnetic induction.

Procedure for measuring pull-off force

We measure using a polished steel standard with a diameter of 10 mm and a height of 20 mm. The measurement is performed at the point with the structurally highest pull-off force - at the pole extensions, or at the lowest point of the arc of the magnetic circuit. We record the force at which the standard detached. We repeat the test 3 times and calculate the average pull-off force.

For your information, 10 N = approx. 1 kg.

As confirmation of measurement and guarantee of the measured values, an original measurement report is issued and included with each magnetic rod, prepared specifically for your particular magnetic rod (the report states the stock and production number).

The magnetic rod complies with the basic requirements of Regulation (EC) No. 1935/2004 of the European Parliament and of the Council of 27 October 2004 on materials and articles intended to come into contact with food.

The product does not contain chemical substances designated by Regulation (EC) of the European Parliament and of the Council as carcinogenic, mutagenic, toxic to reproduction, persistent, bioaccumulative, toxic, and we confirm that they are not included on the Candidate List (SVHC) in a concentration higher than 0.1% by weight according to Regulation (EC) No. 1907/2006 of the European Parliament and of the Council of 18 December 2006 concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals.

WARNING: 

The resulting pull-off force and magnetic induction depend on many factors - e.g. the dimensions of the standard, the air gap between the standard and the tested magnetic circuit, the thickness of the measuring probe, surface contamination, the surface finish of the standard, etc. The stated values of pull-off force and magnetic induction were measured under ideal conditions given by the test environment. However, these values may change depending on the specific type of environment, where e.g. operating conditions and subsequent wear may affect the product’s efficiency and measurement results. The stated values must therefore be regarded as indicative and any deviations from them cannot be considered a defect within the meaning of the provisions 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 carry out your own measurement. If the determined values of pull-off force and magnetic induction are not sufficient for you because they do not correspond to the stated values, you may use the guaranteed option of returning 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 serve precisely for testing the goods, and after this period the seller may refuse to accept the return of the goods.
