15/07/2013 · For any circuit, whether a crushing circuit, a rod mill, or a closed ball mill circuit, the Work Index always means the equivalent amount of energy to reduce one ton of the ore from a very large size to 100 um. The sample was received crushed appropriately for the ball mill test.

Nilsson Wulff (): Crushing in stages, as an alternative to SAG milling, generates the same size reduction but with a lower total power consumption (crushing vs. milling). Rising energy costs and the benefits of cone crushers to reduce operating costs will hopefully shift the landscape in favor of crushing circuits.

I would argue that your theory of marginal cost is backwards. Power production is managed so that the base load, the amount of power that is produced all of the time, is produced by the lowestcost method of generation. Additional power that is required during peak usage times, is produced using smaller generators that can be started up quickly.
