    Influence Of Open Circuit Regrind Milling On Ug2 Ore

    Jul 01 2005 Under the closed circuit milling conditions the circulating loads made operating at relatively high ball loads greater than 25 virtually impossible as the flow through the mill would flush the balls out. Under open circuit conditions the feed to the mill inlet is reduced by up to 60 and the feed density increased to 2.2 tm 3. This allowed for operating at ball loads in excess of 30 and
