There is no increase in size and the additional strength improves removal of very fine iron particles from a wide range of coolants and other liquids. It works the same way as a ceramic coolant cleaner except that it utilizes a rare earth magnet that maximizes magnetic field strength. The resulting high field strength removes particles down to 3 microns. In operation, liquid contaminated with fine ferrous particles enters the sump area and flows past a counter-rotating magnetic drum. Particles attracted to the drum are held tight and lifted to the top, where a mechanical discharge mechanism moves them to a discharge chute.
Cleaner liquid is discharged from the bottom of the separator.
Fine magnetic particles suspended in the dirty liquid tend to flocculate when introduced to the strong magnetic field, thus increasing separation efficiency. Accordingly, this coolant cleaner is effective even on moderate, or paramagnetic particles. The efficiency of magnetic separators, such as this, depends on the magnetic susceptibility and concentration of the contaminants, as well as the viscosity of the liquid. The rare-earth coolant cleaner helps machine tools run longer and maintain accuracy by removing grinding swarf. When machining both ferrous and nonferrous materials on the same grinding machine, an additional level of filtration is necessary.
