The balance between crushing and blasting 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.
