Basis was a SABC circuit of 8 ball charge. Maximum SAG mill power was determined by deducting the installed ball mill pinion power of 7.95 kWh t from the maximum overall circuit power of 16.7 kWh t to give 8.75 kWh t. Overall power for the comminution circuit (SAG plus ball mills) base on a.
Feb 21, 2015 For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over an 8-hour shift, allowing to calculate corresponding to circulating load ratios and circulating load tonnage on tons day or tons hour.
The ball mill has higher circulation load, it generates only 30 -35 of actual fines you require to be called as product. If your product size needed is 100 passing 45 micron, then the ball mill total discharge material will contain normally 30 of 45 micron. The rest is oversize which has to be ground again.
The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
