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. Running a pilot ball mill circuit can overcome this problem but this requires a reasonably large sample and therefore can be costly. In addition a valid scaleup procedure is required.
