SAG Mill Control

SAG Mill Control Semi Autogenous Grinding (SAG) is arguably the most commonly used method of comminution in mineral processing In spite of this many SAG mills do not run at their full potential Primary grinding consumes a significant percentage of plant operating costs and has a significant impact on the performance of downstream process such as flotation Effective SAG mill control
