SORTER FOR GRANULE

A granule sorter is provided to stably sort out granules without blocking up through-holes formed at a sorting sieve of a drum screen by shaking off manure particles stuck on a brush at once by a brushing unit. The granule sorter is composed of a drum screen(100) equipped with a sorting sieve(110) like a mesh net or a perforated net on the outer peripheral surface to pass the inserted particles and rotated by a shaft(130) receiving power of a power unit; a brush(200) installed at one or both sides of the outer peripheral surface of the drum screen and in contact with the sorting sieve to block up through-holes(111) of the sorting sieve and brush off foreign materials; and a brushing unit(300) installed on the other side of each brush coming into contact with the sorting sieve of the drum screen and equipped with plural brushing rods having one end coming into contact with the brush to brush off manure particles.
