Assessment and modelling of quaternary and quinary HPGR

The complexity degree of a mining plant’s comminution circuit is critical for allowing the processing of low-grade iron ore deposits. Considering that the comminution stage is responsible for most of the energy consumption in a mineral processing plant, the pursuit of energy-efficient technologies is a major challenge of the mining industry. The High Pressure Grinding Rolls (HPGR) have been

2015-3-12  Today, the iron-ore industry uses HPGRs to prepare pellet feed for finishing grinding after wet-ball milling and filtering. The wet-ball mill product is more readily filtered without the need to grind it to the final product size. Since HPGRs can process fine ores at moistures of up to 10%, they are used to perform the final stage of grinding.
