HYDROCYCLONE Russian patent published in 2001 - IPC

FIELD: mineral concentration; applicable in ore and coal mining and other industries. SUBSTANCE: baffle plates in hydrocyclone are installed on internal surface of discharge branch pipe and made in the form of upper and lower shortened epicycloids relative to inlet of discharge branch pipe and in cross-section perpendicular to hydrocyclone axis. In this case, total height of shortened epicycloid does not exceed two diameters of cylindrical part of discharge branch pipe. Height of lower shortened epicycloid does not exceed one third of diameter of cylindrical part of discharge branch pipe. Immovable circumference of upper shortened epicycloid is equal to diameter of cylindrical part of discharge branch pipe, and that of lower shortened epicycloid is equal to diameter of circumscribed circumference of upper shortened epicycloid. EFFECT: higher efficiency of separation due to additional withdrawal of fine and light particles. 2 dwg
