Abstract
PURPOSE: To eliminate the segregation, to make the grain size uniform and to increase the effective accommodation by providing a sieve to the material feeder on the upper part of the hopper and by supplying the material from two feeding ports at least, the locations of which are distinct from each other, to the sieve.
CONSTITUTION: The granular material 1 is supplied from feed ports 4A, 4B to areas 11A, 11B of a sieve 11, and is sifted out by giving an oscillation by means of a vibrating device 12. And only the undersized material 1A drops in a hopper 2 at once, the oversized material 1B is advanced and taken from the oversized material discharging port 13 at the lower end of the sieve 11 to the outside of the system, it is reground and reused. Accordingly since only the undersized material 1A is thrown into the hopper, the grain size composition is limited in a fixed range, and since the material drops from the sieve 11 uniformly, any area of the inside of the hopper 2 is made uniform in grain size composition, the material can be contained in the hopper in a flat state to improve the effective accommodation.
