• 18 700 Gauss on the magnetic core and up to 12 200 Gauss on the stainless steel protective cover
  • Better work safety – the magnetic core is an integral part of the separator body
  • Quick and easy installation and cleaning = better comfort
  • Made-to-measure separators
  • Separation of magnetic particles from 1 µm

Magnetic grate separators in housing MRZ

General principle of the function of magnetic separator MRZ

Magnetic grate separator in housing is designed to separate magnetic iron contamination from liquid substances (such as coolants and emulsions for various machining operations).

Design of magnetic separator in housing

The basic elements the magnetic grate separator in housing consists of are magnetic tubes (made from stainless steel). While the liquid material flows aroung 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 above the other inside of the housing (or one behind the other – in case of a vertical position of the tubes) and the first set of tubes consists of one tube less. The grate sieve - created in this way – is in a very intensive contact with the flowing materia, can capture even the smallest ferromagnetic impurities and guarantees an extremely high separation efficiency. For best results the inlet part of the separator can be equipped with dispersion cones that disperse the material flow over the magnetic tubes.

Which way is grate magnetic separator cleaned?

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. During the cleaning the magnetic cores are pulled out of the tubes (either manually or pneumatically) into the upper part of the separator housing. The captured magnetic impurities fall off spontaneously. Thanks to the encased version of the magnetic grate separator the neodymium cores are totally maintenance-free.

If you use our magnetic grate separator in housing, you will improve the quality of your final products, you will be able to use the coolants in a repeated way and in particular we will help to protect your expensive machinery. The dimensions as well as the design of the magnetic grate separator in housing can be adjusted to client's needs.
