DEVICE FOR GRAVITY SEPARATION OF FINE GRAINED MATERIALS Russian patent published in 1998 - IPC

Abstract RU 2101088 C1

FIELD: concentration of noble, rare and non-ferrous metal ores. SUBSTANCE: device for gravity separation of fine grained materials has conical bowl 1 installed for rotation round its vertical axis and provided with annular riffles on the inner surface 2, appliance 3 for feeding the material into the bowl, ripples 7 disposed between the annular riffles of the bowl and made in the form of hollow studs. The ripples are secured horizontally on the immovable pipes disposed inside the bowl in parallel with riffle generators and intended for supplying wash water in the direction of bowl rotation. Facility for discharging heavy fraction is made in the form of V-shaped false bottom. EFFECT: improved efficiency and fine sizing of material. 1 tbl, 1 dwg
