Helping to reduce mining industry carbon emissions: A step-by …
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

Ball Mill (Ball Mills Explained)
If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.Web
