Dry Permanent Magnetic Separator | Encyclopedia MDPI
Dry magnetic separation is a technology that sorts magnetic minerals from gangue using air as the medium instead of water. When raw ore is fed to the magnetic separator, the magnetic particles are subjected to magnetic force due to the nonuniform magnetic field. When the magnetic force exceeds the competitive force (i.e., gravity and …

What is Magnetic Separation?
Raw material or finished product will be fed either by gravity, pumped, air, or conveyor belt in which it passes over or through a magnetic rod, grate, grid, or plate. The magnetic field from the magnetic separator captures ferrous contamination by attracting it while allowing non-magnetic clean products through the manufacturing process.
