ball mill circuit design

Dec 01, 1997 Computer simulation of ball mill cicuits has been found to be very valuable for optimisation where existing plant data can be used to calibrate the mathematical models used. However, as by definition no existing plant is available for calibration in greenfield scenarios, the use of simulation in ball mill circuit design has been limited
