A ROUND SCREEN FOR REGULATING GAP AND A EQUIPMENT USING IT FOR SAPERATING PARTICLE

摘要

A round screen and an apparatus for separating particles are provided to control a gap between neighboring wings of the round screen easily, by interlocking wings, which are rotatively installed between a pair of fixing frames, with saw-teeth of a pair of operating frames so that the gap is controlled by rotating the operating frames. A round screen comprises a pair of fixing frames(110), a plurality of wings(130) positioned between the fixing frames, and a pair of operating frames(120) positioned inside respective fixing frames. Each of the fixing frames has a circle plate with a hollow portion(114), and a plurality of rotating holes(111) formed around the hollow portion. Each of the wings has rotating protrusions(131) formed at both ends thereof, wherein the rotating protrusions are inserted into the rotating holes. Each of the operating frames has a circle plate with a hollow portion(124), and a plurality of saw-teeth(121) formed on an inner periphery of the hollow portion. The saw-teeth of the operating frame are inserted into both ends of the wing.
