Abstract

See full text

An integrally-rotating cylindrical sieve 1 includes a hollow rotating shaft 2, which a driveshaft 21 is inserted into and fixed to, support members 3 radially extended from the rotating shaft 2, a cylindrical sieve body 4 made from a thin plate with a large number of apertures 5 formed therein, such as punching metal, and coupled with the support members 3, and sieve frames 6a and 6b attached to axial ends of the sieve body 4. The rotating shaft 2, the support members 3, the sieve body 4, the sieve frames 6a and 6b, and the driveshaft 21 are coaxially rotated together. The sieve body 4 is a cylindrical corrugated plate having wave crests and wave troughs arranged along its circumference and has a large number of apertures 5 formed in the corrugated plate. This arrangement improves the sieving efficiency of the granular material and effectively prevents potential destruction and cracking of the granular material, thus enhancing the commercial value of the sieved granular material.
