PURPOSE:To enhance magnetic separation efficiency and to reduce power consumption by arranging parmanent magnets to the inside half of a rotary cylindrical body in parallel to the axial direction thereof so that N-poles and S-poles are alternately arranged in the circumferential direction and setting the surface magnetic flux density of the cylindrical body to a specific value or more. CONSTITUTION:Permanent magnets 15 are arranged to the inside half of a rotary cylindrical body 20 and separate the raw material falling from the upper part into a magnetic component and a non-magnetic component. The permanent magnates 15 are arranged in parallel to the direction of a shaft 11 so that N-poles and S-poles become alternate in the circumferfential direction and the surface magnetic flux density of the cylindrical body 20 is set to 300 gauss or more. As a result, a magnetic separator improved in magnetic separation efficiency, reduced in power consumption and having a simple structure can be obtained. |
