Stainless steel separator MV-R

The extremely powerful magnetic separator MV-R is used for the continuous and automatic separation of weakly magnetic pieces of stainless steel, including very small particles.

This extraordinarily strong as well as compact and modular magnetic separator consists of a vibratory feeder and a pair of rollers. The drive roller is magnetic (with a rotational speed control according to the character of cleaned material and working needs) and the driven one is non-magnetic. This roller pair is mutually connected to each other with a very thin, but extremely sturdy polyurethane belt  (which is also suitable for food applications, antistatic and has increased temperature and mineral oil resistance). The magnetic field of the magnetic cylinder reaches a maximum height of about 10 mm. It is therefore advisable for the material transported on the belt not to exceed a height of 10 mm. At the same time, the material should be poured on the conveyor belt as an evenly thick layer and distributed properly (e.g. by a vibrating hopper). Ferromagnetic particles are trapped by the magnetic field of the roller and brought behind its axis, whereas the cleaned (i.e. non-magnetic) material falls off at the separator outlet (due to gravity). Thanks to a special flow divider of the magnetic and non-magnetic material (angularly and axially adjustable) it is also possible to separate even the third fraction from the pure material. The third kind of the material can be found between the pure material and the ferromagnetic contaminants (thus it involves the lightly magnetic material, i. e., partly contaminated with iron particles).

Please bear in mind that primary stainless steel is mostly non-magnetic. However, industrial usage and processing (machining, pressing, crushing, repeated impacts, heating, etc.) disrupt the non-magnetic crystalline lattice of stainless steel, making it weakly magnetic (compared to conventional iron or steel, machined stainless steel is only magnetisable within a few percentages, and can therefore only be captured by an extremely strong magnetic field). The highly inductive magnetic cylinder is therefore designed for the most demanding industrial clients requiring the separation of even very weakly magnetic stainless-steel particles. The operating capacity of the separator also depends on the maximum size of the stainless steel particles (the separation capacity of the magnetic separator is proportional to the size of the stainless steel particles, i. e., the smaller the particle, the more difficult for the separator to capture it).  MV-R reliably separates weakly magnetic particles of as small as 0.1 mm, but it can randomly capture stainless steel particles as small as 30 microns. The separator is available in widths of working space from 500 to 1 500 mm.

Thanks to the material quality used, when producing the magnetic roller (combination of extra strong NdFeB magnets with special steel washers and the very thin but highly sturdy conveyor belt) this top separator is able to achieve a surface magnetic induction up to 21,000 gauss. This is a value, which has been reached so far only by electromagnetic separators. On the other hand, let us bear in mind that the reached value of the magnetic induction of the magnetic roller is not so important as the density of the magnetic poles, because the MV-R is often used for catching small ferromagnetic particles. Should the distances between the magnetic poles be too large (in order to achieve the maximum magnetic induction), the very strong magnetic field generated in this way will not be exploitable for catching tiny impurities – because these would slip through due to big distances between the magnetic poles. Therefore, in combination with the very dense poling the optimum value of the magnetic induction on the roller surface ranges about 11,000 gauss (to achieve the maximum capture also of very small ferromagnetic particles).

Besides the high efficiency of the magnetic separation, the other advantages of this top-ranking separator are the low power consumption, low operating costs, a wide range of applications (including food processing), high durability and modularity (it can be easily integrated into existing processing lines or equipped with additional accessories like e. g. a vibration feeder).

The high gradient permanent magnetic stainless steel separator MV-R is used for cleaning and recycling of e-waste, incinerator bottom ash, heavy fractions from crushing lines and is applied for recycling of metals in general.

Extra value added

Magnetic force (induction) generated by the extremely strong permanent magnets from rare earth ores does not let through any unwanted ferromagnetic impurities – and that is why the application options of our products are nearly unlimited (they find their use in chemical, plastic, automotive, building and pharmaceutical industries, food processing, mining etc.).

Our company goal is not only to manufacture and deliver a product, but above all to find and offer an exact solution satisfying the requirements and needs of just YOUR company. In these days of rapid changes in technology it is very difficult to keep up with the latest trends even in the field of your own activity, not to mention other industrial or foreign branches. And that is why we offer you our technical support based on our know-how and our experience. We hope that you - as well as our present clients - will also appreciate our assistance with solving problems regarding the separation of magnetic particles from your products, that we will help to protect your expensive machinery and that our solutions will make your production process even more fluent. If you are looking for a solution of a problem with separation or detection of ferromagnetic impurities in your goods, do not hesitate to contact us. We can help you.

Free magnet audit

Free magnet audit is an exceptional service thatSollau_serviceman.jpg

  • checks the function of the magnetic separator (if the tramp metal is effectively trapped)
  • examines if the magnetic separator fulfils its potential and meets application requirements
  • evaluates the effective pull, the status, the location and the cleanness of the applied magnets

During the audit, we do not only inspect your magnetic equipment, but we also

  • provide training on care and maintenance of magnetic separators
  • suggest the measures to be taken in order to improve the operating efficiency of the magnetic separation related to your products and materials
  • identify the key areas in your company where the application of magnetic separators could enhance the operating performance, reduce operating costs, purify the product or protect processing equipment from metal damages

Audits are conducted by SOLLAU specialists that - in co-operation with the client - develop an audit plan and determine priorities. During the audit, the auditor physically inspects and measures the effective strength of the magnetic separator. He also photographs and documents the state of the device. After the check is completed, the auditor issues a detailed report including the results of the effective strength findings. The inspection results are also important references for internal quality assurance and help analyse biological, chemical and physical hazards (HAACP) as well as ensure high quality production (QA).
