Get PriceThe typical closed ball mill circuit to which CSE analysis can be applied is shown in Fig. 1. The extreme importance of the circulating load ratio (solids tonnage through the mill vs. the circuit) in determining circuit productivity was demonstrated by Davis (1925) and published by Gaudin (1939), as shown in Fig. 2. The circuit production rate As an example, GRPGM for platinum (Pt) in the ball mill-cyclone circulating load was about 80%. The cumulative selection functions of Pt and palladium (Pd) were ca. 1.3 times higher than the solids for size fractions above 212 m, which moderated their buildup in the closed circuit, but were ca. 60% that of the solids below 212 m which ...
Get PriceIf you need to add water to the feed end of your ball mill to control the density, by all means do so, but make sure you decrease water addition by an equal or greater amount elsewhere in the circuit (e.g. SAG feed or cyclone feed) or the overload will continue to escalate once the immediate benefits are overtaken by increased circulating load. The feed from the fine ore bins is sampled, and is found to contain 5% moisture. The cyclone feed contains 33% solids, the cyclone underflow 65% solids, and the overflow 15 % solids. Calculate the circulating load on the circuit and the amount of water required to dilute the ball mill discharge.
