ROLL SCREEN FOR COKE SORTING

摘要

FIELD: metallurgy. ^ SUBSTANCE: device for coke screening includes an inclined frame with a dividing surface assembled thereon; the said surface represents shafts with disks arranged on the shafts in a staggered order and distance rings, forming screening cells. A nominal width of disks located at least in the middle part of the shaft from the coke supply side is increased by 1.125-1.25 times. A nominal diameter of disks is increased at a value of their thickening. ^ EFFECT: increased service life of a screen. ^ 4 cl, 2 dwg, 1 tbl
