Pipeline magnetic separators for pneumatic conveying lines MSP-S
The magnetic grate separator for use in vacuum and pressure conveyor pipes is designed to separate magnetic iron contamination from a rapid stream (up to 25 m/s) of liquids or dry substances of good bulk properties.
Design of pipeline magnetic separator
The basic elements the magnetic grate separator in housing consists of are magnetic tubes (made from stainless steel). While the material flows around 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 sets of tubes are placed one behind the other and the first row of tubes consists of one tube less than the next row. The grid 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 metal particles captured on the magnetic tubes migrate to the rear of the tubes where they remain protected from wash-off until the tubes are cleaned. To maximise the efficiency of the separation process, the pipeline magnetic separator MSP-S is fitted with ultra-strong neodymium magnets.
This separator is equipped with a set of magnetic cores hermetically sealed in stainless steel tubes (= magnetic bars) that are inserted into a protective stainless steel grid (consisting of a set of stainless steel tubes). Thanks to the protection of the magnetic cores by two stainless steel tubes.
This “tube-in-tube” system offers several advantages:
- long lifetime of the costy magnetic cores (protection from water, mechanical wear during the cleaning etc.)
- elimination of the contamination risk (of the cleaned material by a piece of a chipped magnetic core or its surface coating)
- enhanced abrasive resistance of all the magnetic grid
We are able to manufacture this magnetic separator with the maximum induction of 13 500 G on the core and 10 500 G on the magnetic pipe sheating. Tolerance is +/- 10 %.
Which way is pipeline separator cleaned?
The strong magnetic field (generated by the neodymium magnets inside the stainless steel tubes) traps all ferromagnetic particles on the surface of the magnetic grid. In the course of manual cleaning the inner part of the separator is taken out of the piping system, the magnetic bars are pulled out of the protective tubes and the captured magnetic impurities fall off the outer stainless steel tubes spontaneously. In case of bigger pipeline magnetic separators (or if the cleaned material is considerably contaminated with ferromagnetic particles), we recommend the use of some of the models with automatic or semi-automatic cleaning (e.g. MSP-AC, MSP-AC EKO or MSP-SC EKO).
What pipeline is the separtor connected to?
In order to ensure a quick and easy connection to the pipeline, the separator housing ends with flanges (standard or customised ones) in diameters from 50 to 200 mm (but we can adjust the connection type as well as its size to client's requirements).
We offer the separator MSP-S with three different surface finishes:
- sandblasted (Ra 1.6 µm)
- internally polished (Ra 0.14 µm)
- fully polished (Ra 0.14 µm)
Is designed to separate magnetic iron contamination from a rapid stream (up to 25 m/s) of liquids or dry substances of good bulk properties.
Which industrial branches can the pipeline magnetic separator be use of in?
The pipeline magnetic separator finds use in food industry (for cleaning products like flour, sugar, starch etc.), pharmaceutical industry, plastic industry, chemical and ceramic industries as well as in sanitary facilities.
