Method and apparatus of stratification with tangential feed

摘要: Method of separation a mixture mineral grains with differentiated sific gravity, under the conditions restricted sedimentation, in cylindrical device, consists therein that A water is radially supplied to trough 2 formed around upper edge wall 1 box. The circulating desludged and partially separated according weight grains, then, pulsating action water, displaced ring-shaped working along spiral trajectories towards conduit 17 19 taking out light fraction D conduits flap 16 for discharge heavy C. motion effected by compressed air being cyclically fed chamber 6 via pulsation valves 14 from tank 5 arranged From additional chambers 7 extend beneath sieve deck 7.
