Ball mills in HPGR-Ball mill circuits tend to have more installed capacity than their counterparts in AG/SAG-Ball mill circuits. This is because the product size distribution from AG/SAG mills tends to have more fine material than the HPGR circuit product ( Morrell, 2009, Morrell, S., 2011 ) and hence need less ball mill power.Web
