HYDRAULIC PLANETARY CONCENTRATOR Russian patent published in 1997 - IPC

FIELD: beneficiation of fossil materials, mainly ores of nobles and precious metals. SUBSTANCE: concentrator includes power drive with shaft 3, bowl 11 and casing 6 with inclined bottom and outlet passages. Power drive is made in form of hydraulic turbine 30. Pressure line 31 of turbine 30 is provided with flow regulator 33. Blades 32 of turbine 30 have different length. Shaft 3 ma be made as crankshaft. Pressure line 31 of hydraulic turbine 30 may be provided with pulsator. This makes it possible to transmit rotation from power drive directly to bowl 11 and casing 6 without intermediate members, thus simplifying the construction and enhancing its reliability. Use of hydraulic turbine 30 as power drive makes it possible to adjust rotational speed of bowl 11 through change of flow rate of water fed to blades 32 of turbine 30 by means of flow regulator 33 and pulsator 39. EFFECT: simplified construction and enhanced reliability. 4 cl, 2 dwg
