INDUCTIVE MAGNETIC FILTER FOR DRY TYPE MAGNETIC SEPARATOR OF ULTRAHIGH MAGNETIC POWER

摘要

PURPOSE:To improve the efficiency in capturing pulverous ferromagnetic powder by providing many ferromagnetic material bars each having a suitable cross section, apart from each other, within the many horizontal planes spaced from each other and deviating the positions of the ferromagnetic material bars within the adjacent horizontal planes relatively from each other in a horizotal direction. CONSTITUTION:When a material B to be treated is supplied through a chute 4 in an arrow direction, the material is supplied through a supply groove 3 opened in a vertical yoke 11 at the upper part to an inductive magnetic filter 7 around a rotary disc 5 which is horizontally rotated by a motor 6. Many ferromagnetic material bars 30 each having, for example, a circular cross section, are arranged apart from each other at a spacing P1 on one plane I in the inductive magnetic filter. Three pieces I , II, III of such planes are perpendicularly arranged apart from each other at a spacing P2 respectively and the bars 30 are provided with a deviation in a horizontal direction P1/2. The ferromagnetic material K in the material B is adsorbed on the bars 30 and is separated from the filter 7 by the compressed air from a nozzle 8.
