Acoustic emissions monitoring of SAG mill performance
Jul 15, 1999Abstract: Particle grinding is a final stage in the comminution process used to liberate minerals from gangue in mineral processing plants. Semi-autogenous grinding (SAG) occurs in tumbling mills which use both large ore particles and steel balls for grinding. Grinding is the most energy intensive mineral processing unit operation and hence its optimisation is of considerable interest to industry.

SAG mills walk a tightrope of loading efficiency. On the one side, overloaded mills mean inefficient ore reduction, naturally leading to increased energy consumption. On the other side, an underloaded SAG mill leads to an increase in critical impacts, causing damage to critical media and mill liners, and resulting in costly repairs and downtime.
