Invention intended [dl] of [obogashcheni] of the slightly magnetic concentrates of different species can widely [ispolzovats] before that mining, glass, food, light, chemical and other industrial [otrasl] x. to the technical result of [otnosits] the expansion of the range of [ispolzovani] of a magnetic separator both during the enrichment of species with the isolation of weakly magnetic fraction and during further enrichment of species to [polucheni] of clean nonmagnetic concentrate via [ispolzovani] before the device of the magnetic system of in the form leading magnetic shaft, [sosto] of [shchego] from post [nnykh] annular magnets, inverted to each other by similar poles and [chereduyushchikhs] through one with the ferromagnetic concentrators in the form of annular pole pieces, and also an increase in the effectiveness of [obogashcheni] of weakly magnetic concentrates via [primeneni] of a durable hyperfine conveyor belt, not [prep] to the [tstvuyushchey] multipolar magnetic system to act on the species by poly-gradient magnetic field with the maximum for example by [zhennostyu]. The technical result of [dostigaets] of [blagodar] so that before the magnetic separator, which includes slave and guide rolls, latter it is supplied for the sake of drive. Device contains the conveyor belt of [dl] of [peremeshcheni] of bulk materials, magnetic system, SV [zannuyu] with one of the shafts and [sosto] [shchuyu] from the unit post [nnykh] magnets. Separator is supplied for the sake of the frame, on which are fixed the shafts, axis of which SV of [zany] with the frame with the aid of the bearing units. Beyond the shafts is located [snabzhenna] of menses by torus Nath marry the conveyor belt, [vypolnenna] from the durable material with the thickness of belt 0, 05-1 mm. guide roll forms the horizontal- formed magnetic system in the form of cylinder, [sosto] of [shchego] from post [nnykh] annular magnets from the rare-earth alloys, inverted to each other by similar poles and [chereduyushchikhs] through one with the ferromagnetic concentrators in the form of annular pole pieces. The end planes post [nnykh] annular magnets of [perpendikul] of [rny] to the axis of magnetic shaft and are rigidly fixed on it with the aid of the end limiters, and the ratio of the thickness of magnet to the thickness of the pole piece of [nakhodits] before the relationship : hn/[N]m=1/10, where hn - thickness of pole piece; [N]m - thickness of magnet.
