FIELD: concentration of ground ores and sands and technogenious wastes in mining industry and metallurgy. SUBSTANCE: proposed concentrator includes load-bearing bed frame with chassis mounted on it, belt-type table at adjustable angle of longitudinal and transversal inclination secured on chassis and eccentric oscillation drive connected with chassis. Unit for change of trajectory of swinging of belt-type table is made in form of slides secured on chassis and mounted on bearing rollers which are secured on bed frame. Chassis fixed on rollers by means of springs is connected with eccentric drive by means of connecting rod. Elastic belt is provided with sides over longitudinal edges for wet concentration; each side has slots directed at angle relative to axial line of belt; each part of side between slots is applied by its end on beginning of next part. EFFECT: increased productivity; enhanced efficiency of extraction of concentrates at dry and wet concentration of minerals possessing different properties. 4 cl, 11 dwg, 3 ex |
