Frozen charge detection and automatic loosening with gearless mill ..., The Frozen Charge Protection (FCP) works on the basis of monitoring the expected torque characteristic of the mill load during start-up.

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 shell.
