Acoustic emissions monitoring of SAG mill performance

Acoustic emissions monitoring of SAG mill performance

Abstract 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.
