As a general rule, the larger the reduction ratio that a comminution device is required to achieve, the less efficient it is. Comminution machines can be much more energy-efficient if they target a smaller size range, i.e. F80 to P80. Therefore, a really energy efficient circuit may mean three stages of grinding instead of only two and each ...

One way to save energy is by blasting more and crushing/grinding less. This way you can reduce the feed size before primary crushing, increasing circuit throughput and reducing the energy required for downstream comminution. Blasting is the most cost-efficient means for ore size reduction. Chemical energy is cheap as opposed …

In-pit crushing and conveying can bring energy efficiency to your plant. Not only is there a benefit in terms of reduced energy consumption in the mills, but the cost to convey material out of the pit also goes down proportionally to the amount of material rejected. It's simply a matter of looking at holistically.
