Abstract
Method and device of separating materials of different density by ferromagnetic liquid, using the separation zone formed by a set of magnets disposed so as to form a V-shaped gutter with both of the pole faces thereof. Objects to be separate are moved crosswise to the gutter by forming the separation zone extending in the range of the opening portion of the V-shaped gutter in such a manner that the separation zone is sloping in a plane across the gutter. This permits separation of materials of larger size in comparison with prior methods. The device is suitable for separating materials having larger size such as scraps of automobile containing aluminum and its alloys having a relatively large size and adapted to be separated from other heavy materials such as copper, zinc and their alloys.
