When looking at overall crushing circuit design, having the correct number of crushing stages also helps minimize fines production. A typical crushing circuit will generate a reduction ration between 5:1 and 7:1 for maximum efficiency. For example, to generate a 10mm particle, you'll want to feed the crusher particles between 50 and 70mm.

The high-grade iron ore is defined in terms of iron content. In general, cut-off iron content of ROM for such type of ore is kept at approximately 55%, which is obtained by selective mining. The ROM ore is subjected to dry/wet processing through multistage crushing and screening for production of lumps (−40+10 mm) and fines (−10 mm). In …
