Declining ore grades, fine grade ores and the environmentally sustainable use of water are major challenges facing not just the iron ore industry but, increasingly, the entire mining industry as well. It needs energy-efficient grinding circuits to offset increasing costs. The polycom dry finish grinding concept in combination.Jul 07, 2016 The HM X-Mill is particularly suitable for the fine grinding of ores and regrinding of concentrates and tailings. It produces a consistent particle size with 100 of the ground material passing 100 mesh (150 μm). The HM X-Mill uses no grinding media which reduces operational costs and avoids contamination related performance issues.
