Abstract

1512750 Sorting solids YAKUT NI I PROEKT INST ALMAZODOBYVAJUSCHEI PROMYSHLEN "YAKUTNIIPROALMAZ" and LENINGRAD N PROIZVODSTVEN OBIEDINENIE "BUREVESTNIK" 30 Nov 1976 49814/76 Heading B2H [Also in Division G1] In an ore separator, e.g. for separating diamonds from a wet mixture, the mixture is fed to a rotating bowl 4, Fig. 3; the rotation breaks up lumps in the mixture and removes water, while distributing the mixture in a thin layer inside the bowl. The upper region of the bowl is irradiated with X rays 10 from sources 7, and luminescence from wanted components of the mixture is detected by photocells 8. As the wanted components are thrown out of the bowl, they are deflected into a chute 15 by air jets 12 actuated by the photocells. The mixture is fed into the bowl via pipe 2. The bowl has baffles 18 in its lower part; the bowl is parabolic, except for the upper region which is conical. The apparatus is closed at the top by a plate 6 having annular slots 10, 11 for the passage of X rays and luminescence. Equations are given for the velocity of particles in the bowl, and for the angular position of the air jets relative to the photocells.
