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

12%The moisture and, consequently, balling control have a starting point at the comminution process, where several types of equipment is applied in iron ore operations. The comminution process based on HPGR generates a higher fines proportion compared with the ball mill circuit by breaking down the minerals due to the pressure applied over the ...

A method of grinding a mineral-containing ore, which includes grinding the mineral-containing ore in a primary milling process and thereafter fine grinding the mineral-containing ore in a secondary ball-mill. A composite grinding medium comprising a mixture of steel balls and pebbles is used in the secondary ball-mill. The pebbles have an average size which is relatively smaller than the ...

Iron ore feed load control is one of the most critical settings in a mineral grinding process, directly impacting the quality of final products. The setting of the feed load is mainly determined by the characteristics of the ore pellets. However, the characterisation of ore is challenging to acquire in many production environments, leading to poor feed load settings and inefficient production ...
