ABSTRACT:
A magnet drum mechanism of a magnet separator includes a cylindrical drum, a magnet provided inside of the drum and forming a magnetic field region configured to adsorb magnetic particles in a circumferentially partial range of an outer peripheral surface of the drum, and a scraper provided in a nonmagnetic field region of the drum, the scraper being configured to guide the magnetic particles adsorbed onto the outer peripheral surface of the drum to an outside of the separator main body in the nonmagnetic field region. The scraper includes a front end portion which faces the outer peripheral surface of the drum in a contactless manner along an axial direction of the drum, and a small gap is formed between the front end portion and the outer peripheral surface of the drum.
