Dry 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 …Web

consumption ranged from 20,000 Btu per ton produced for a concrete stone plant to 54,000 Btu per ton for a plant producing fine agricultural limestone as well as grade stone. The average for the 20 plants was 33,500 Btu per ton. 1 Very few studies similar to the NSA report have been generated since that time. Table 9-1.Web
