PROCESS COMPLEX FOR UNLOADING AND CARRYING SAND-GRAVEL MIX TO SAND-GRAVEL CLASSIFICATION CIRCUIT WITH SEPARATION OF GRADED SAND AND GRAVEL

摘要

FIELD: transport.;SUBSTANCE: invention relates to mechanised complexes for unloading, grading and carrying of loose cargo. Proposed complex comprises hydro scheme 1 with underground pump 3 with intake branch pipe 6 and casing 12, hydraulic cyclone, hydraulic screen 35 and hydraulic classifier 34. Tube to feed water for sand-gravel mix wash-out is connected to outer side of casing 12. Hydraulic cyclone communicates with hydraulic classifier inlet via damper 37 wherein said is separated into two fractions. Gravel is graded into three different factions and fed onto belt conveyors.;EFFECT: higher efficiency of sand-gravel mix unloading, carrying and grading.;5 cl, 1 dwg
