If ball milling was completely replaced by HPGR, up to 50% of the energy needed for the dry grinding mill could be saved. In wet grinding, the energy savings are lower, yet still noticeable. Further to the reduction in energy costs, the HPGR also proved to produce higher quality grinding products and/or a better recovery.
