PROBLEM TO BE SOLVED: To provide a screen for an electromagnetic separator which reliably magnetically attracts magnetic foreign matter by narrowing an interval for causing powder to pass therethrough, increases a magnetically attracting area for magnetically attracting the magnetic foreign matter thereto and can prevent clogging of powder or magnetic foreign matter.SOLUTION: A screen 1 for an electromagnetic separator used for the electromagnetic separator which magnetically attracts and separates magnetic foreign matter contained in powder includes a ring-shaped ring frame 2 and a wedge wire screen 3 fixed into the ring frame. Therein, the wedge wire screen 3 is formed by subjecting all intersections between wedge tip parts of wedge wires 6 of which the vertical cross-section shape is wedge-shaped and support rods 5 to electrical resistance welding and is formed of an annular penetration part 7 through which a retention bar for retaining the screen 1 passes at the center. |
