Comminution Circuits for Gold Ore Processing - ScienceDirect

Depending on circuit configuration, large single-line secondary/tertiary crushing lines have a nominal installed power of 3 MW, and the capacity to crush 25 to 40 ktpd per line. A typical large cone crusher (with applications in crushing circuits, pebble-crushing circuits, and secondary crushing for feed to HPGRs) is depicted in Figure 17.7.
