For proper function, the purified bulk mixtures (material that you pour over the magnetic rod) must have the following properties:

• Homogeneous
• Dry with good flow properties, non-sticky, so that the material 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. 

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 suitability of using this magnetic rod or to select another magnetic separator. 

The magnetic rod is used as a pre-stage to protect technology so that ferromagnetic contaminants do not enter equipment that they could damage, for example mill knives, crushers, nozzles of regranulation and granulation lines, injection molding machine nozzles, extrusion presses, pressing stations, presses for wet pressing, shredding equipment, fine sieves, ceramic pressing stations, glass presses, etc. It can also be used to purify a mixture to the highest possible cleanliness (meaning removal of ferromagnetic admixtures), where the magnetic rod is placed at the end of the production process just before packaging, dispatch, handling/transfer, so that no contamination occurs during subsequent operations in the production plant. In this case, it is assumed that the purified material is immediately sealed into closable packaging or other closable containers. Thanks to the very high magnetic force, there is a high capture rate of ferromagnetic contaminants (please read the detailed description below of what sizes of ferromagnetic contaminants this magnetic rod will capture).

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 to any flat steel plate or into another auxiliary structure designed by you. No auxiliary structures, flat steel plates, holders, or fastening materials are included with 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 the magnetic rods will be made; likewise, fastening materials must be non-magnetic. The minimum distance between rods after installation on your auxiliary structure/holder/flat bar must not be less than 20 mm. This is for safety during installation and also to prevent the rods from being pulled together by magnetic force. Also consider the properties of the material (bulk and liquid) to maintain the required flow rate/throughput. If you design auxiliary holders for magnetic rods yourself, we cannot assume any responsibility for the correct function of the magnetic rods. If you are not sure about the installation or assembly into the form of a magnetic grate, do not buy the magnetic rod and contact our technical-sales department. We draw attention to the very high intensity of magnetic force. Take extreme caution when designing and manufacturing your own assembly for placing multiple magnetic rods next to each other, and especially when screwing them (any assembly) into a set—separate individual magnetic rods from each other with a non-magnetic spacer, e.g. a wooden board. There is an increased risk of injury when the magnetic rods connect! Keep all magnetic materials, structures, and tools such as hammers, pliers, vices at a minimum distance of 200 mm from the magnetic rods. Also watch out for the workbench—it must not be iron (ferromagnetic)!

You can also use the magnetic rod on its own by directly placing it freely into the material, both into dry material and liquid material. It is resistant to moisture, so it can be immersed (partially or even completely) in liquids. Do not insert the magnetic rod and do not 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 min. 6.5 to max. 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 suitability of using the magnetic rod, or a recommendation of another product from our range.

The magnetic rod can also be used for magnetic separation from bulk mixtures (from dry material). Hang it freely, place it, position it in the place you consider best for the function of this magnetic rod. You can also mount it anywhere using a screw. The screw is not included with 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 metal magnetic material acts on the magnetic rod permanently, its force is reduced, e.g. if the magnetic rod were installed very close to a ferromagnetic beam or placed into 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, chutes, troughs, slides, various similar structures) do not use this magnetic rod. Contact our technical-sales department for more information, confirmation of suitability of using the magnetic rod, or a recommendation of another product.

You can therefore use the magnetic rod in an assembly of several magnetic rods or on its own, as stated either for liquids or for dry mixtures. Below we list examples of materials for which you can use the magnetic rod to separate metal magnetic contaminants (magnetic separation).

Note: all liquid materials must meet the pH requirements from min. 6.5 to max. 8.5; all dry bulk mixtures must meet the maximum material size stated in this text (diameter 0–3 mm, max. size 3x3x3 mm); 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 contaminants, do not use this magnetic rod and contact our technical-sales department to recommend a suitable product for your purposes.

We point out that the wall (housing) thickness 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 you will pour the material onto the magnetic rod (impact height) when using the magnetic rod for bulk material. In general, the impact height should not exceed 1 m. However, this is individual for each type of material. When pouring from a great height, the stainless cover 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 technical-sales 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, unmeasurable, magnetic dust) up to a diameter of 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 expected, but in this case it represents the maximum size of a ferromagnetic metal contaminant. Larger objects must not fall onto the magnetic rods (larger objects must not flow through the magnetic rods) than stated (max. diameter 3 mm, 3x3x3 mm). If you are concerned about the presence of larger ferromagnetic metal or other contaminants/admixtures, it is necessary to install a sieve with a mesh size of max. 3 mm upstream so that these larger unwanted objects are captured before contacting the magnetic rod. The sieve is not included with the delivery of the magnetic rod. We also point out the possibility that your material (dry or liquid) may contain a very large amount of fine metal contaminants (very fine metallic magnetic dust) that can “coat” the magnetic rods and, in the case of an assembly of multiple magnetic rods next to each other, block the assembly. At the same time, the magnetic force will be greatly reduced—this also applies to a magnetic rod used on its own. If the magnetic rods immediately become coated and completely “hidden” in iron dust, this is not a defect of the magnetic rod; magnetic separation must be strengthened with 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 metal dust in your material), do not use this magnetic rod and contact our technical-sales department to recommend another type of magnetic separator or to approve the use of this type.  

Magnetic rods are designed to capture as many metal magnetic contaminants as possible. However, everything depends on the amount of these magnetic contaminants present in your material. It is not possible to bindingly guarantee the capture of all magnetic contaminants. It is always necessary to consider the specific technology and capacities. If necessary, additional types of magnetic separation must be placed upstream or added. Please do not rely only on this single magnetic rod. If you need advice, contact our experts in magnetic separation at any time.

Do not use the magnetic rod to separate stainless steel (generally referred to as “stainless”), even if it appears magnetic (for example after passing through various crushers or after other forms of deformation; it may also be used to manufacture various screens). The magnetic rod is not intended for separating non-ferrous non-magnetic metals, nor for separating parts or their components that contain metals (e.g. plastic parts with embedded remnants of metal parts, crushed windows with remnants of metal strips, wood pellets with embedded fine wires…). If you need to separate such metal magnetic contaminants as well, contact our experts in magnetic separation at any time; they will advise which other magnetic separator to use or what type to add to your separation assembly.

We point out that during cleaning of the magnetic rod, it is possible to use pressurized water only from a maximum distance of 300 mm from the magnetic rod. You can soak and rinse the magnetic rod during cleaning (with ordinary water only). You can also use a dry cloth for cleaning or well-dried compressed air to blow off residual metal contaminants and separated material. When manually wiping metal magnetic contaminants, the use of protective work equipment is required. Be careful when cleaning an assembly of multiple magnetic rods.

This magnetic rod is not intended for use in any environment classified as an explosive atmosphere (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 location with the highest structural magnetic induction – at the pole pieces or at the lowest point of the magnetic circuit arc. The test is repeated 3 times at different locations of the magnetic circuit and the average magnetic induction is calculated.

Procedure for measuring pull-off force

We measure using a polished steel reference sample with a diameter of 10 mm and a height of 20 mm. The measurement is performed at the location with the highest structural pull-off force – at the pole pieces or at the lowest point of the magnetic circuit arc. We record the force at which the reference sample 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 as a guarantee of the measured values, we issue—and every magnetic rod includes—an original measurement report issued specifically for your particular magnetic rod (the report states the stock and production number).

The magnetic rod meets 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 that are classified by Regulation (EC) of the European Parliament and of the Council as carcinogenic, mutagenic, reprotoxic, 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 pursuant 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 reference sample, the air gap between the reference sample and the tested magnetic circuit, the thickness of the measuring probe, surface contamination, the surface finish of the reference sample, etc. The stated pull-off force and magnetic induction values were measured under ideal conditions defined by the test environment. However, these values may change depending on the specific type of environment, as operating conditions and subsequent wear may affect the effectiveness of the product and the measurement results. Therefore, the stated values must 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 and magnetic induction values are not sufficient for you because they will 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, the seller may refuse to accept the return.
