Steady state conditions were achieved by maintaining the relative standard deviation (RSD) of the circuit operating variables such as AG/SAG throughput, cyclone feed flow rate, cyclone pressure, mill power draw and water addition below 5%. The plant was held at steady state condition for at least two hours, prior to conducting a survey. 2.1.

Stirred media mills are influenced by a great number of operating variables. A study was conducted to understand the influence of mill speed, feed particle size and, slurry density and rheology on the VXPmill performance. For scale-up, a study was conducted to compare the batch recycle and the pendulum testing procedures.
