Permanent magnetic filtering device

Permanent magnetic coolant filtering devices are used to filter and clean FE particles automatically from contaminated coolants (emulsions, aqueous solutions as well as cutting and grinding oils) accumulating at the processing machines.

The coolant to be cleaned must be run settled (laminarly) over the entire width of the feeder, since this achieves a high degree of filter efficiency. The coolant passes the magnetic roller in radial direction. The FE particles and particles adhering to the ferromagnetic parts are attracted and discharged by the rotating rollers. The adjustable stripping plate is positioned diagonally on the roller and allows the carried liquid to flow back while the particles are removed from the roller dropping into the collecting tank. Our compact, space-saving plants ensure an extremely high functional duration while being virtually maintenance.

Cleaning the coolant has the following advantages:

  • Improving the workpiece surface and dimensional accuracy
  • Extended service life of tools and grinding discs
  • Minor reject rates
  • Less frequent renewing of coolant lubricants
  • Skin diseases are prevented
  • Lines no longer clog
  • Pump wear is minimised

Permanent magnetic filtering devices of the series consist of:

  • a stable and robust special steel housing
  • a feeder with an adjustable baffle plate
  • a magnetic roller with powerful permanent magnets
  • an adjustable gap narrowing sheet controlling the flow efficiency and the filtration result
  • an adjustable, wear-resistant stripping plate
  • a maintenance-free worm gear motor
  • Deviating from our standard plants, accessories and special designs are available.
