Working principles The contaminated coolant from the machine is fed into the inlet of the magnetic filter. As it passes thru the gap between the drum and the body, The dust particles are arrested by the drum. A synthetic rubber roller is mounted on springs, sqeezes the dust and allows only dry powder, Which is further scraped out from the drum by scraper and is collected in the dust collecting tray. The level of filtration will be almost 95 % for ferrous particles. These filters can be used with all types of grinding machines such as cylindrical, Centerless, Internal, Surface, Double disc and roll grinding machines. These can also be used for filtered honing oil of honing machines, EDM's, Washing machines., Features ? Uses rare earth magnets which provide upto 8 tines the magnetic force of conventional ferrite magnets. ? No consumables required. Dry cake discharge. ? Excellent efficiency even for seperating materials having weak magnetic properties, such as carbide and scale. ? Superior contamination removel means improved surface finish, increased life of grinding wheel, reduced dressing frequency, increased life of fluid. ? Kind to environment, Kind to the pocket.
