A particle size reduction model has been developed as the first component of an upgraded ball mill model. The model is based on a specific energysize reduction function, which calculates the particle breakage index, t 10, according to the sizespecific energy, and then calculates the full product size distribution using the t 10 t n relationships and the masssize balance approach.

There are three types of grinding media that are commonly used in ball mills: • steel and other metal balls; • metal cylindrical bodies called cylpebs; • ceramic balls with regular or high density. Steel and other metal balls are the most frequently used grinding media with sizes of the balls ranging from 10 to 150 mm in diameter [30].

Abstract. 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.
