摘要
A magnetic metal removing device for color sorting apparatus includes a hollow feeding roll. Within a hollow portion of the feeding roll, a magnet is arranged such that it closely opposes to a part of an inner surface of the hollow feeding roll to form a magnetic force active surface on the corresponding outer surface of the feeding roll. Magnetic metal mixed in raw granular objects is attracted on the magnetic force active surface. The magnetic forced active surface changes to a magnetic force inactive surface as the feeding roll rotates. The magnetic metal caught on the feeding roll is released from the magnetic forced inactive surface and colleted by a collecting device.
