ORE SEPARATING COMPLEX FOR MECHANICAL CONCENTRATION OF MINERAL RAW MATERIAL AND METHOD OF ITS OPERATION Russian patent published in 2003 - IPC

FIELD: equipment for preliminary mechanical concentration of minerals, gold-bearing ores for example; geotechnologies. SUBSTANCE: proposed complex includes conveyer 12 for delivery of material from crusher 24 to screen 26 and sections for fine-batch separation 28 and lump-by-lump separation 30 having stage consisting of at least two separators 36 loading devices 38 where flow is formed at delivery which is lesser than initial. Sections 28 and 30 are provided with supply units 40 and material accumulator 46 of operational store corresponding to difference of initial and set supplies in form of bin 52 with unit 54 supplying material to return conveyer 56. Simultaneously with separation, circulation is performed for return of material of operational store and/or part of material in the amount exceeding productivity of lower separator of stage to beginning of flow forming zone. EFFECT: improved quality of product; increased productivity; enhanced efficiency of concentration. 10 cl, 6 dwg
