Case Study

We believe the projects that we have executed speak for themselves. CITIC HIC has engineered and provided 6 AG mills of Ø12.2m×11m (28000kW gearless drive) and 6 overflow discharge ball mills of Ø7.9×13.6m (2×9000kW gear drive) for Sino Iron Project in Australia. For Zijin Mining’s Duobaoshan Copper Mine project in Heilongjiang, we have manufactured and provided SAG mills of Ø11×6.4m (2×9000kW) and overflow discharge ball mills of Ø7.9×13.6m (2×9000kW) which have been well operating currently.
