hpgr ball mill final feed in kenya

Today the ironore industry uses HPGRs to prepare pellet feed for finishing grinding after wetball milling and filtering The wetball 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
