The technical field to which the invention relates. The invention relates to a device for magnetic separation with a freely falling material. The level of technology Closest to the invention to the technical nature of the electromagnetic separator, gravity, magnetic, containing the electromagnet with pole pieces (see patent RU No. 2376070). In a known separator removable blocks have progredient plate, conductive plates, magnetospheric that is hard massive structure. This requires the creation of a large, non-uniform magnetic field with a high value of the magnetic induction and leads to an increase in the number of magnet wire coils, and, consequently, to the increase of power consumption. When applying a DC voltage on the coil there is no possibility of changing the voltage received from the rectifier, which does not allow to regulate the process of separation for different production conditions. In addition, the pipeline is constructed in a vertical position, which makes it impossible to use it in industrial processes where separation of the products is in an inclined pipeline, and therefore leads to the restriction of the use of the separator. Cleaning of the magnetic particles is removed from the interpolar is prostranstva plug-in units, without turning off the voltage on the magnetizing coils. This increases power consumption, and removing blocks is time-consuming non-mechanized process that leads to great work. Disclosure of the invention. The problem to which the invention is directed, is to increase the efficiency of the material of the magnetic core, winding, and lower consumption of magnet wire, the efficiency of purification from the magnetic particles. The technical result consists in increasing the inhomogeneity of the magnetic field, the approximation of the separated product to the hub and the decrease in the number of turns of the winding, the increase of the magnetic induction on the hub. The technical result is the following set of features: electromagnetic separator, gravity, magnetic, containing the electromagnet with pole pieces, characterized in that it contains a control unit, bumpers mounted on the bottom of the pipeline, cover the pan with handle, covering the pole pieces, in addition, the electromagnet equipped with magnetizing coils mounted on the cores that are pole pieces. The task, which directed the claimed invention, and the technical result interrelated as education is. Increasing the inhomogeneity of the magnetic field, the approximation of the separated product to the hub and a reduction in the number of turns of the winding, increasing the magnetic induction at the hub increases the efficiency of the material of the magnetic core, winding, reducing the consumption of magnet wire, increases the degree of purification from the magnetic particles. Brief description of drawings 1 shows an electromagnetic separator, gravity, magnetic, side view, figure 2 - electromagnetic separator, gravity, magnetic, top view.
