ABSTRACT:
A magnetic separator conventionally includes a conveyor belt (1) that forms a closed loop around a magnetic roller (2) and an idler roller (3) to convey a mix of materials (4), the novel aspect being that the belt (1) is not driven by the roller (2) but by the idler roller (3) that is motorized, and in that the belt (1) is not wound directly on the roller (2) but on an idle tube (3′) of non-magnetic material inside which the roller (2) is arranged with a minimum gap. It is therefore possible to obtain two surfaces with a relative slip and therefore two different speeds whereby the attracted material, during the path defined by the 180° of tangency to the magnetic area, due to the backing or advancing of the magnetic polarities tends to rotate backward or forward with respect to the travel direction of the belt. This results in substantially all the inert material being released and falling by gravity in a first fall area (5) located below the vertical tangent to the belt (1), and also in a progressive release of materials with increasing permeability, with a fan-like detachment that leads them to fall into distinct fall areas (6, 7, 8).
