Associate Professor Mohsen Yahyaei

Its effect on grinding rates can be studied in a pilot scale mill and/or by analysis of industrialscale mills surveyed at different times. The outcomes could be used for SAG Mill modelling and for optimising the grate relining and mill speed control strategies employed on mine sites. Develop a mathematical model of the discharge capacity.
