The enriching device, which contains the means of the supply of pulp, the means of giving to it rotary motion, at least two coaxial cylindrical cowlings, one of which is partially placed in the cavity of another with the clearance, whose lower section opened beside the circular groove, supplied for the sake of unloading branch pipes, that is characterized by the fact that the means of the supply of pulp is executed in the form the receiving conical funnel, coaxial with the cowlings, the diameter of vent of which corresponds to the diameter of the section of the cowling of the greatest cross section and it is reported with it; moreover the means of giving rotary motion to pulp is executed in the form tangential relative to the housing of the receiving conical funnel of the branch pipes, oriented before the direction of action beyond the pulp of the force of the rotation of the earth and blade swirl vane, made in the form of the blades, fixed, before the internal surface of cowlings, with the possibility of twisting pulp before the direction of action beyond the pulp of the force of the rotation of the earth, in this case one of the walls of circular groove is formed by the appropriate section of the wall of the cowling of the smaller size of fixed in the cavity, superincumbent cowling, furthermore, each of the circular grooves is reported with the separate vibration concentrator by means of the separate distributive bunker. The use of the declared useful model ensures an improvement in the quality of the enrichment of material and ensures simplification in the construction of device, its production and operation. 3 illustrations.
