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.
