How does Magnetic Separation work? In summary, the raw material or finished product is fed either by gravity, air, pumped or conveyor belt where it passes through or over a magnetic rod, grid, grate or plate. The magnetic field captures the ferrous contamination by attracting it to the magnetic tube or plate.
