返矿是烧结矿筛分后的筛下产物,它是由小颗粒的烧结矿和一部分未烧透的生料组成。我厂返矿分热返矿和冷返矿两种。热返矿是SZR1545热振筛的筛下物,采用BR1700热返圆盘定量配到混合料皮带上;冷返矿来自两部分:烧结成品系统筛分的筛下产物,包括中间料仓和烧结料库的返矿,其余为高炉槽下过筛的筛下产物。在烧结混料中配加一定数量的返矿,可以改善混合料的粒度组成,有助于烧结过程
The return ore is a sieved product of the sinter, which is composed of small particles of sinter and a portion of unreinforced raw material. I returned to the mine sub-heat returned to mine and cold mine two. Hot return mine is SZR1545 heat shock sieve under the sieve material, the use of BR1700 hot round disk quantitative allocation to the mixture belt; cold return from two parts: Sintering Finished products sieved sieve products, including intermediate silos and sintering Restock ore library, and the rest of the sieve under the blast furnace sieve product. In the sintering mixture with a certain amount of return to the ore, can improve the composition of the mixture size, contribute to the sintering process
