Iron Ore Crusher Machine. Iron ore crusher machine is a powerful machine that divides the iron ore, which exists unprocessed in nature, into small pieces to process after extraction.
Whereas this design suits the mining process and is operationally simple, there can be little confidence in the grade of the ore that is fed to the crusher. This makes short-term grade control difficult and reconciliation back to the mine face imprecise. Well-designed and operated pre-crusher stockpiles can overcome these deficiencies.
Within mining, pre-crusher stockpiling is often used for its operational simplicity, but it typically lowers the confidence of the ore grade and reduces certainty in feed quality [15].
