High Pressure Grinding Rolls (HPGR) | TENOVA

The high pressure comminution process causes micro-cracks in the particles, which lead to the liberation of minerals and a higher portion of fines. HPGR treated minerals show better leaching performance, because the micro-cracks increase the particle contact surface for the leaching liquid.

Comparing energy efficiency of multi-pass high pressure ...

The operating work index method for comparing comminution energy efficiency underestimated HPGR performance due to the large amount of fines generated. The -75 µm efficiency factor and F50/P50 reduction ratio interpolation methods both give results that were more credible because they better took into account the amount of fines generated by HPGR.
