Rods are also generally more expensive than balls and harder to handle. This means a rod mill equal in capacity to a ball or SAG mill would take up more plant floor area requiring a larger building. ... The pairing mill combination of a SAG/Ball mill is common in copper/gold mines for that reason. This combination can aim for a fine product ...

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.
