Jul 3, 2017 Capacities and efficiencies in wet and dry ball milling at different speeds and ore charges have been discussed in the foregoing pages. The results are The difference is in accord with the right side of table 17, where a small ore charge received the better selective grinding when the feed was dry. The ore
Apr 29, 2016 Such a step would require the use of dry rather than wet grinding systems. Traditionally, dry grinding systems have been only an exception in mineral processing, since most post grinding processes are wet. However, there are successful, mainly ball mill based, dry grinding examples in gold, nickel and iron
