  • Developments in HPGR technology - Mining Magazine

    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.
