Title:
SCREENS FOR ELECTROMAGNETIC SEPARATOR
Document Type and Number:
WIPO Patent Application WO/2011/086793
Kind Code:
A1
Abstract:
Screens for an electromagnetic separator for separating iron powder contained in powder, the screens having increased iron powder collection efficiency which is obtained by increasing the area to which the iron powder is magnetically attracted and also by increasing the number of the screens to reduce the amount of iron powder which passes through the screens without being magnetically attracted to the outer peripheries of the screens. Screens for an electromagnetic separator are supported in multiple layers in the vertical direction within a tube which is disposed at the center of the electromagnet of the electromagnetic separator, and the screens consist of a magnetic material which magnetically attracts iron powder contained in powder supplied from the opening in the upper part of the tube. The screens (1) for an electromagnetic separator have formed at the center thereof circular through sections (3) through which a holding bar for holding the screens (1) pass, and the screens (1) also have ring frames (2) formed on the outer sides thereof.
Each of the ring frames (2) has disposed therein a spiral plate (4) and a wave-like wave plate (5), the spiral plate (4) being spirally wound toward the through section with a gap between the turns, the wave-like wave plate (5) being disposed between the turns of the spiral plate (4). The crests and troughs of the wave plate (5) are affixed to the spiral plate (4).
