Magnetic grate separator in housing MSS-MC

Magnetic grate separator in housing MSS-MC

A magnetic grate separator is designed to separate in a quick and easy way magnetic iron contamination from free-flowing substances of good bulk properties and to protect the machinery that subsequently treats these materials.

The basic elements of the magnetic grate separator in housing are one or two rows of magnetic grates (consisting of stainless steel tubes). While the material flows over the magnetic tubes, a very strong magnetic field (generated by the neodymium NdFeB magnets inside of the tubes) traps all metallic particles on the surface of the tubes. The magnetic grates inside of the housing are placed one above the other and the upper set of tubes consists of one tube less. The grate sieve - created in this way – is in a very intensive contact with the flowing material, can capture even the smallest ferromagnetic impurities and guarantees an extremely high separation efficiency. The captured metal contaminants are pushed to the underside of the tube where they are out of contact with the product flow preventing washoff back in to the clean material.

In order to ensure a quick and easy connection, the separator housing is standardly ended by flanges (standard type, Jacob quick-connect fasteners or flanges according to client's needs) in sizes from 100 to 300 mm, but we can adjust the connection type as well as its size and the inbuilt height to client's requirements.

We offer the magnetic box separators in three different surface finishes:  

  • sandblasted (Ra 1.6 µm)
  • internally polished (Ra 0.14 µm)
  • fully polished (Ra 0.14 µm)


We deliver MSS-MC in several variants:


The uniqueness of the technical solution of this model consists in the system of the magnetic grate moving on telescopic slides and also in the extraordinary protection of the magnetic cores. Thanks to its placing on the guiding drives, the entire magnetic grid is an integral part of the magnetic separator and handling the magnetic grid as well as and the magnetic bars (during the cleaning) is therefore effortless. Besides, the magnetic cores are permanently protected by a special accordion cover, simultaneously performing three functions during the separator cleaning:

1. It prevents unwanted skipping the ferromagnetic contaminants from the surface of the stainless steel grate onto the magnetic cores.
2. It protects the magnetic cores e.g. before dusting (with the cleaned material, etc.).
3. It eliminates the risk of contaminating the cleaned material by e. g. a piece of a chipped magnetic core or its surface coating.


The separator is also provided with inspection holes (sight glasses) on the sides, so that both the material flow and the amount of captured Fe contaminants can be visually checked.

On a special request, the separator can also be equipped with a shutting flap for a manual interruption of the material flow into the separator, with a safety lock etc.


This is a conventional design where the magnetic grates are installed crosswise with respect to the entrance door. The material flow as well as the tube contamination status can be checked thanks to an inspection window.

The grates can be taken out of the separator (e. g. for cleaning) and afterwards cleaned very easily and quickly (as the ferromagnetic particles drop away off the grate tube surface spontaneously as soon as the magnetic cores are manually pulled out of the stainless steel tubes).



This innovated separator has the magnetic grates placed parallelly to the door opening, unlike the standard grate separator. The advantage of this design consists above all in the fact that the separators of larger dimensions can be equipped with guiding bars which will make heavy magnetic grate handling easier (it is not necessary to take it fully out of the separator body for cleaning). Moreover, the internal structure of this special separator has been modified in order to limit undesirable material accumulation in any part of the separator (which is important e. g. in order to comply with the strict hygienic requirements referring to food processing or pharmaceutical applications).


MSS-MC EKO 100 N a008a.jpgThis budget-wise version of the box separator does not offer all options provided by standard magnetic box separators, however, on the other hand, it has several indisputable advantages. It is ideal for applications in piping systems where MSS-MC or MSS-MC IN could not be installed because of height limitations (the installation height of MSS-MC EKO is only 50 mm, so this separator can be used nearly at any application place). Both-sided standard JACOB flanges ensure easy and quick fastening and that is why hopper outlets, tube end pieces for big bag filling etc. are very suitable fields for the application of MSS-MC EKO (and its selling price is also very attractive). Its disadvantages consist in a lower capacity (it is only a single grate separator with narrower tubes, and that is why it is suitable for less contaminated materials) and the necessity of taking the separator out of the piping system during the cleaning (of course, only if it is installed in a pipeline and not e. g. at a hopper outlet). 


This special grate magnetic separator is fitted with exceptionally robust (but at the same time also lightweight) steel flange, it has a very low built-up height and is provided with a flap for manual interruption of the material flow into the separator. All these parameters predefine this separator for the plants or lines where the central interruption of the material flow into the separator could be problematic or unsuitable. The robust design at the same time guarantees that the separator will resist to even very high weight load. Other parameters are similar as those of MSS-MC IN, i.e. the separator has magnetic grates mounted in the direction of entrance door opening so that the grates can be pulled out from the separator for cleaning and cleaned easily a quickly. The separator is intended primarily for piping applications in the plastic industry (it is to be positioned in front of injection moulding presses, extrusion machines, etc.).


It is an economical but at the same time fully functional version of the magnetic grate separator for applications in JACOB piping systems. The separator is terminated on both sides with JACOB flanges (with the diameter ranging from 50 mm to 300 mm), however, when compared with standard grate separators, it is cheaper, lighter and has also a lower built-up height. Moreover, a round body of the separator ensures smooth flow of material through the separator (undesirable material sticking or accumulation inside of the separator does not take place). The separator has magnetic grates mounted in the direction of entrance door opening so that the grates can be pulled out from the separator for cleaning and cleaned easily and quickly. Thanks to the termination with the JACOB flanges, this separator has multi-sector utilization (it can be applied e.g. behind exhaustion device or dust separator).

Magnetic box grids are mostly used in the area of recycling and waste treatment, food processing, pharmaceutics, wood processing, plastic industries, mining and mineral processing, industrial production of ceramics and glass etc.

  • 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).
