A total of 6 parallel lines process 9500 t/h of ore. Screening equipment is installed after the primary crusher, after the scrubber and after the tertiary comminution stage to separate the iron ore into a dry coarse fraction (8 – 40 mm) and a wet fine fraction (> 1 – < 8 mm). The fraction < 1 mm passes through another washing stage.

(SPI®) and Crusher Index measurements. The SPI® is a measure of the hardness of the iron ore from the perspective of semi-autogenous milling. The CEET Crusher Index (Ci) is used to predict the SAG feed size distribution of the ore, and is measured during the SPI® feed preparation procedure. It requires 10 kg of minus 2-mesh material that is

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 …
