Measurement of Steel Ball Impacts Inside a SAG Mill

In large-scale mining, SAG (Semi Autogenous Grinding) mills are widely used. These mills use steel balls that go up to 6.5" in diameter and have a high risk of fracturing the internal linings of the mill. Potential impacts of the steel balls against the mill lining will be generated if the rotational speed of the mill is greater than that ...
