Types Of Charges In Sag Mill

Robust estimation and protection of locked charge in

This condition is usually named frozen load and the load remains locked to the mill shell and after a half turn drops damaging the mill body and bearings Therefore the mill protection system must give an early detection of this condition and aborts the start before the compacted mill charge falls hitting the bottom of the mill
