Enduron HPGR Screens
Screening HPGR discharge material often requires a large screen. A typical HPGR circuit operates with up to a 200% recirculation load, resulting in high screen feed rates. The cut size of a typical HPGR screen range from 1 - 4mm. This requires much larger screens than those used in typical mining applications or attributed to other screen profiles.

Why gold mines are adopting HPGRs to increase production …
How HPGR improves gold recovery. There are two main ways mines recover gold ore from the gangue, and HPGRs can assist with each process. One of them is heap leaching and for mines using this process, we've found that the most efficient setup is to have a HPGR perform tertiary grinding immediately prior to recovery, completely avoiding the use of a …
