CENTRIFUGAL CONCENTRATOR Russian patent published in 2003 - IPC

FIELD: material concentration, for instance, ores concentration in mining, chemical industries and in manufacture of building materials. SUBSTANCE: centrifugal concentrator has rotor connected with bowl located in its cavity and having internal surface with hollows and holes for injection of liquid to hollows from devices of its supply through rotor hollow shaft and cavity between walls of rotor and bowl, and device for loading of concentrated material into bowl whose overflowing side member is adapted for unloading of light fraction. Axle of rotation of rotor with bowl assumes one of positions in rotor relative to horizontal within inclination angle of 10 dwg when rotor with bowl is raised above horizontal, and to inclination at an angle of 45 deg when tray are lowered below horizontal. Installed under bowl overflowing side member is branch pipe for unloading of heavy and light fractions with turning to respective position for unloading. Hollows of bowl internal surface may be formed by circular riffles. EFFECT: higher efficiency of concentration process due to simplified effect of segregation of separated particles and higher operating reliability due to simplified design of apparatus. 2 cl, 5 dwg, 1 tbl
