FIELD: metallurgy. ^ SUBSTANCE: technological complex includes hydraulic cyclone block with distributor of suspensions in the form of pulp, electric driven pump, suction and delivery pulp lines, coarse crushed ore supply conveyor, fine ore crushing mill, particle-size classifier, sump, technological water supply system, shutoff and control valves and automatic control and monitoring system. Each hydraulic cyclone is made in the form of cylindrical conical housing with receiving chamber in upper part, which is connected by means of feed branch pipe to pulp distributor, and equipped with cover plate with drain branch pipe and sand head piece combined at the bottom with similar header with similar head pieces of other hydraulic cyclones. Mill is connected at the inlet to coarse grained ore receiver and at the outlet to particle-size classifier having two outlet channels by means of which the latter is interconnected via fine fraction of ore with sump, and by means of the other one it is switched to mill in recirculation manner. Sump is interconnected via T-piece and suction pulp line with delivery technological water supply pipeline with possibility of controlled change-over to washout of pulp in sump, and turbine pump is interconnected with similar delivery pipeline in adjustable manner. ^ EFFECT: increasing efficiency and improving the quality of ore suspension separation as per fractions at reduction of power costs, increasing stability and operating life without stops for repair and replacement of quick-wearing parts; improving hydraulic cyclone designs. ^ 5 cl, 6 dwg |
