How HPGRs compare to conventional milling

 · As a result, ball mills produce a rather wide particle-size distribution (PSD), requiring additional work downstream, while rod mills achieve a lower PSD but produce a coarser product. By comparison the inter-particle compression in a High Pressure Grinding Roll has a more even effect on the entire feed, resulting in a high ratio of fines without the wide PSD.
