Granule feeding method and feeder

Abstract

Abstract PURPOSE:To solve a clogging problem on screw loading as well as to make the quantitative feed of small or very small quantity performable, by conveying and feeding granules with a difference in conveying quantities by two screws different in diameter and in conveying direction each, and being set up concentrically. CONSTITUTION:A motor 6 is rotated, a support part 2 is rotated as well, thereby two spring screws 3 and 4 in reverse of each winding method and different in diameter are rotated. Under this state, granules P are charged from the charging port 1a of a casing 1, and these granules are conveyed in a white arrow direction by the spring screw 3, while they are conveyed in the black arrow reversible direction by the spring screw 4. In this case, if the spring screw 3 is made larger in diameter than the spring screw 4 and its pitch is properly designed, the conveying quantity by the spring screw 3 becomes larger, so that these granules are smoothly conveyed to the right as a whole.
