1.       formed of mainframe, ore-discharged device, ore-concentrated chute, chute & rack

2.       large disposal capacity, high recovery efficiency, save electricity

3.       install conveniently, good economic benefit

4.       principle is as follows: mainframe is installed in chute, ore pulp inflow from one end of chute, the magnetic in ore pulp is absorbed on disc surface through the gap between discs, the non-magnetic ore pulp inflow from another end. When the mainframe disc operates, the magnetic minerals absorbed on disc surface comes from ore pulp. Ore-discharged device pour the magnetic minerals on disc surface into ore-concentrated chute, and collected by ore-concentrated chute.
