CENTRIFUGAL VIBRATORY CONCENTRATOR Russian patent published in 2002 - IPC

FIELD: mineral concentration from sands of placer deposits and ground ores, and in processing of sand-clay refuse former mining. SUBSTANCE: centrifugal vibratory concentrator has working member in the form of bowl rotated with deviation of rotation axis from vertical by means of driven part of drive mechanism, flexible member displacing in horizontal plane, and limiter of bowl inclination angle. Mutually contacting surfaces of bowl and its limiter are made for self-installation of bowl for working regime of planetary vertical or close to vertical rotation with maximum displacement of driven part of flexible member equalling the difference between diameters of mutually contacting surface. Concentrator has pivot for bowl. Connection of bowl with pivot ensures forced touch of mutually contacting surfaces. Flexible member is located for taking up without vertical load. EFFECT: higher reliability and efficiency of concentrator due to increased recovery of minerals by intensified material segregation in bowl interrifle grooves. 2 dwg
