概述大多数细粒的烧结用矿石原料需要选别,以满足用户对其化学成分和粒度组成的严格要求。在这方面,对于选别-1毫米的细粒弱磁性铁矿石,琼斯磁选机起主导作用,因为它生产能力高、效果好且经营费用低。本文阐述如何采用该类型磁选机使已单体解离的大约-4毫米的粗粒铁矿石,富集成高质量的烧结给料,条件是琼斯磁选机安装上比目前使用的齿槽更大的极板,即采用间隙宽为6毫米的4R-极板。当给矿中微细物料含量低时,经一次选别,就能选出铁品
Overview Most fine-grained ores used in sintering require selection of raw materials to meet the stringent user requirements for their chemical composition and particle size composition. In this regard, the Jones Magnetic Separator played a leading role in sorting fine-grained weakly-magnetite ores up to -1 mm because of its high production capacity, good results and low operating costs. This paper shows how this type of magnetic separator can be used to enrich about 4 mm of coarse iron ore, which has been monomer-dissociated, into a high quality sinter feed provided that the Jones Magnetic Separator is installed on a larger than currently used gullet The larger plate, which uses a 4R gap plate width of 6 mm. When the content of fine materials to the mine is low, after a sorting, you can choose iron products
