Batu Hijau has a dual-line grinding mill circuit, two SAG mills, followed by two closed-circuit ball mills per SAG mill and a combined pebble crusher circuit. The SAG mill is fed with crushed ore from the mine with 80% passing (F80) 50 to 70 millimetres (mm). The typical throughput capacity of Batu Hijau's grinding circuit is 4,000 to 6,000
