Grinding of material in HPGRs has proven to be more cost efficient as compared to conventional mills and crushers. Especially downstream processing stages such as ball-milling are more energy-efficient with an HPGR due to the finer product size distribution coming out and the additional effect of micro cracks within the product particles.
