Magnetic solution

In case of magnetic rods to be used with textile filters, MAGSY offers several magnetic induction / magnetic force levels. According to a type of the material flowing through the magnetic rods, suitable magnetic force should be selected. Our experts will recommend you the force level appropriate, in a coordination with your production environment and technological possibilities knowledge.

In some separation applications, deeper magnetic circuits must be chosen in a way that metal impurities are partly attracted even from a longer distance.
After that, they have to be firmly caught which applies to magnetic separation cases where larger ferromagnetic impurities are dealt with mainly. On contrary to that, in some applications, the magnetic circuit depth should be reduced as much as possible, in a way that the “clamping” force is the highest as it could be so even the finest ferromagnetic impurities (having a slimy mud characteristics) are caught and held reliably. This all must be provided in a combination with a very thin wall separating the liquid from the magnets; in most cases, the thickness ranges between 0.5 and 0.7 mm based on the magnetic force selected and magnetic separation quality requirements.

More about the magnetic induction measurement and our magnetic rod parameters

However, in any case, as close as possible metal impurity contact with the magnetic rod in question must be provided. In case of textile filters, there is usually hard to find this out so the contact with magnetic rods is compensated by a longer time for which the liquid remains in the candle filter. Amongst others, this impacts to an increase of technological times. Because of that, our company also offers a possibility of the magnetic separation improvement, by an installation of two magnetic rods into a specially modified magnetic rod holder. Due to that, the time to be spent in the filtration unit does not have to be extended so the probability of ferromagnetic impurity catching becomes increased just due to the quantitative stiffening of the magnetic rods in the holder. For a sake of completeness, you may download a graph where it is displayed how the magnetic induction and tear-off force values decrease as a function on a distance from the magnetic rod. This confirms the fact that more rods installed increase the probability of ferromagnetic impurity catching.

Technical solution

Magnetic rods are installed in specially designed holders developed directly for most of the filter dimensions, capable of containing one or two magnetic rods. In a comfortable and ergonomic way, the holder fits to the groove located in the candle-like filter, so during its installation, the maximum tightness of the entire system is guaranteed. The number of rods to be installed is given by the production technology and customer requirements regarding the outgoing magnetic separation – see the section above.

We manufacture magnets for textile filters in the design featuring one or two magnetic rods:

Magnet for textile filters, with one rod

Magnet for textile filters, with a single rod (MTF – 1) – it consists of one magnetic rod + stainless-steel carrier for that rod

Magnet for textile filters, with two rods

Magnet for textile filters, with two rods (MTF – 2) – it consists of two magnetic rods + stainless steel carrier for the two rods

Magnetic rods

Final surface treatment uses polishing, with the final surface guaranteed for the polish level of Ra = 0.02µm – in order to achieve as smooth as possible surface by the reason of prevention of creating micro-fissures where impurities may accumulate, making thus unwanted „crusting“ effect. This 100 % smooth surface also guaranties very comfortable and trouble-less cleaning.

In the lower magnetic rod part, there is situated a pin-like projection the location of which is comfortable and precise – magnetic rod is installed into its holder.

In the upper part, an embedment is designed providing perfect securing of the magnetic rod during its installation into the auxiliary holder.

A specially designed, so called open magnetic circuit, with a shorter or longer arch between the pole extensions, guarantees a maximum magnetic – tear-off force corresponding to your needs.

The material is a standard stainless steel 1.4301 / AISI 304. By request, if needed in environments characterized by aggressive pH values, we can supply the product as made of the 1.4404 / AISI 316 material. All materials are in the quality corresponding to respective EU norms and possessing respective certifications.

As a standard, magnetic rod temperature resistance is up to 80 ˚C. By your request, we can prepare your magnetic rod also for using at higher temperatures, i.e. up to 200 ˚C (in case of even higher temperatures, please take into account decreasing of our standard magnetic parameters by ca 10 – 20 %, as depending on the thermal resistance chosen).

Magnetic rod holder

Holder surface treatment uses ceramic ball blasting – this results into a unique, matt surface. In general, the design is robust, firm, and it enables less careful treatment as well.

In the upper part of the magnetic rod holder, small telescopic piston is situated. The item provides a fixed magnetic rod securing in the holder and, also, its very comfortable removal upon cleaning.
Perforated, lightweight stainless steel partition is very important part of the magnetic rod holder. Especially by safety reasons, the partition serves to provision of perfect separation of the magnetic rods (in case of cleaning) that applies to the variant including two rods installed.Magnetic rods are very strong and they may NEVER become connected with each other (please, pay an extraordinary attention to their handling – if interconnected, they can be separated again only with a difficulty). In addition to that, your fingers may become injured too.

Magnetic rod cleaning

After the magnetic rod has been removed (in case you afford the arrangement including two magnetic rods, please remove the rod in question from the holder in its axis direction. In respect to the fact that the magnetic circuit is ended to a sufficient extent before the rod end on both of the magnetic rod sides, metal impurities fall out very easily. However, it is very important to carry this process out using a personal protective equipment, in order to prevent hand injuries by sharp metal impurities that can also be collected on the rods.

Magnetic rods – main benefits:

• Good magnetic output of separate rods due to strong NdFeB magnets
• Minimum magnetic output losses due to a thin, worked pipe wall.
• The product has flexible dimensions. MAGSY manufactures magnetic rods according to dimensions given by customers.

Non-comfortable system of magnetic rods cleaning from Fe impurities is a disadvantage. The cores cannot be pulled out.Pipe wall is machined to as low as possible thickness, in order to minimize the magnetic force losses. Magnetic core consists of cylindrical NdFeB magnets and pole extensions.

Standard magnetic parameters of MAGSY rods are on the three levels.

As a standard, MAGSY manufactures MR magnetic rods in two diameters and several lengths.

• MR with the diameter of 25 mm: the lengths are 150; 200; 250; 300; 350; 450 and 500 mm
• MR with the diameter of 30 mm: the length is 250 mm.

Magnetic rod cleaning is always manual. Wipe Fe impurities off from the rod surface by hand.

Customers prefer magnetic rods mainly in certain grate dimensions. Own grate is made by customers by themselves.

Magnetic rods are made-on-measure by MAGSY in various lengths and flexibly, based on a submission.

Magnetic rods – industrial utilization areas

1. Use in dry materials

In fact, MR magnetic rods, as parts of magnetic grates, may be used in all industrial areas where the medium to be cleaned is represented by a dry, homogeneous material, or dry material mixtures in very small or fine fractions. Good loose parameters need to be provided at all times.

Grates made of magnetic rods are not suitable for using with abrasive media because the pipe wall is machined to a very small thickness so the tear and wear of the pipe may come very quickly. This deals also with materials with adhesive behavior. Rod-made grates are usually stationary, i.e. the grates may become clogged due to the material “arching”.

Utilization areas:

• Agricultural product industry, feeding mixtures, especially food industry
• Building matter industry, ceramics and porcelain industry, chemical industry
• Polymer and rubber processing industry and other industrial areas where dry, loose bulk material is processed.

WARNING
Due to the facts that separate rods are supplied per order and the customer creates his magnetic grate by himself, the question of so called “fall labyrinth” is not solved on the MAGSY side. This indispensable condition of a proper separation efficiency is solved and covered by the MAGSY company only in cases of separators belonging completely to the company portfolio (MST, etc.).

Size models and separator design

MF-UP is a standardly manufactured product by the company MAGSY. It is designed for connecting to circular pipelines, in the following sizes:

DN: 50; 65; 80; 100; mm

The separator is connected to pipelines using standard connecting elements, flanges.

If the MF-UP separator is used, the utilization is normally aimed at the protection of own product – medium.

From the magnetic equipment point of view, MF-UP is manufactured on the magnetic induction levels of I – VI.

MF-UP magnetic cores are vertically movable within the component. The system enables a possibility of a comfortable and quite good system of the pipe cleaning from Fe impurities. At the same time, the system provides the magnetic core protection against an  erosive action in liquid environments.

Main benefits of MF – UP separator:

• Cascade flow – due to the fact that the incoming and outgoing holes are located on different positions, more efficient material flow through the magnetic separator takes place, and this results into the maximum utilization of the whole magnetic pipe length.
• Magnetic induction of up to 17,000 G – on all magnetic pipes. Yu can choose the magnetic induction level of I – VI.
• All magnetic pipes with the diameter of 30 mm – in comparison with competitor product, already in our standard production portfolio, we offer all pipes with the diameter of 30 mm
• Magnetic pipe replacement possibility – magnets located in the separator are protected using stainless steel cases. In case of damaging, you can replace these covering pipes with new ones quite easily. Due to that, this separator is also suitable for more demanding environments (abrasive materials, etc.)
• Possibility of the magnetic core locking – due to the possibility of the manipulation handrail locking, there is no risk of the production sabotage by an intentional pulling the “cleaning handrail” during the entire manufacturing process.
• Possibility of the cleaning preparation supplying – by the reason of an easier manipulation during magnetic pipe cleaning, we can supply you the cleaning preparation that is made to measure of your magnetic separator.

MAGSY is competent in designing proper separator type and model including its magnetic output and labyrinth corresponding to a given separation task. The knowledge of the operational conditions, medium and Fe impurity parameters is needed for that.

Cleaning preparation used with MF – Classic and MF – UP

MAGSY, as a manufacturer of separators, is strongly focused on simplifying of the cleaning techniques of own separators, improving thus the cleaning comfort.

In order to simplify own manual separator cleaning, MAGSY manufactures the cleaning preparations being offered as an additional, facultative separator equipment.

Cleaning preparation used with the MF-classic and MF-UP serves to simplify the cleaning process, to increase the cleaning comfort and, last but not least, to improve the working safety on the separator magnetic component handling.

The material:  stainless steel 1.4301

Working procedure using the cleaning preparation

1. The component is dismantled from the separator body, and it is relocated to the cleaning preparation seat. Telescopic mechanism pull bar remains inserted in the lower position, i.e. the cores are in the lower pipe position. Fe impurities are still held on the pipe surface using the magnetism. Not pulled = the cores remain in the lower pipe position.
2. Mechanism pull bar is pulled up to the upper position. This way, also the magnetic cores are relocated to the upper pipe space in the component. This leads to the magnetic field relocation to the upper component space, and the pipes in the separation area become demagnetized.
3. Due to that, the magnetic field that previously held separated Fe impurities on pipes, is interrupted. Then the impurities fall out spontaneously to the garbage cup.
4. Fe impurity residuals, still occurring on the pipes (due to just a weak para-magnetism), are cleaned easily using a brush.

Cleaning preparation utilization area

• Increase the cleaning comfort
• Working safety improvement, it helps keep the workplace clean and tidy
• Magnetic core durability increase

• DN: 50; 65, 80, 100 mm

The separator is connected to pipelines using standard connecting elements, flanges.

According to the magnetic separation task, i.e. the protection of technology, or the protection of a medium product, and also based on the task operational conditions, the separator may be additionally equipped with various magnetic core compositions, from the magnetic output viewpoint. This can be done on all six standardized levels.

This means that either there is prioritized the magnetic induction value, or there is a need to prefer the tear-off force value. According to these criteria, core composition on the levels I. to VI. is selected.During the cleaning operation, an attention must be also paid to the carefulness from the working safety point of view. Careless handling = danger of hand finger injury.
