factors affecting the performance of the sag mill mining machine

Sag mills are the main workhorses in the majority of comminution circuits globally they need to be fed and kept working round the clock but challenges can arise when capacity is not optimised causing unnecessary downtime and liner wear leading to the one sound operators do not want to hear the sound of the mills standing still
