WhatsApp: +86 18221755073Dry processing of iron ore: In dry processing of iron ore, ROM is generally crushed below 40 mm through three-stage crushing and thus segregated by screening into 10–40 and −10 mm fractions. For softer ore, tumbler index is generally low and hence lump ore is crushed below 10 mm to produce fine product. Yield from the plants has been ...
WhatsApp: +86 18221755073The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed.
