<P>PROBLEM TO BE SOLVED: To obtain a magnetic substance-sorting apparatus that enables continuous operation without the need of stopping it for the purpose of removing sorted magnetic substances, that has no fear of dropping of the magnetic substances by an impact or the like when the granular body is charged and of re-mixing into the granular body, and that is simply structured and made available at a comparatively low cost. <P>SOLUTION: The magnetic substance-sorting apparatus includes: a fixed center shaft 11 in which magnets 111 are arranged in a part of the surface of at least the upper half portion along the longitudinal direction; and a spiral body 12 which is concentric with the fixed center shaft 11 and is composed of a non-magnetic body rotating around the fixed center shaft 11. In the apparatus, there is also provided a spiral conveyor 1 that transfers, in the longitudinal direction of the fixed center shaft 11, the magnetic substances 32 attracted to the surface of the upper half portion of the fixed center shaft by the rotation of the spiral body 12, as a magnetic substance sorting means. <P>COPYRIGHT: (C)2011,JPO&INPIT |
