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.

Elemental chromium (Cr) does not occur in nature, but Cr exists in chromite ores as FeOCr 2 O 3 . There are some processes to obtain Cr from chromite. For all processes milling process is essential. In milling process of chromite, ball mills are generally used, because followup processes need fine particle size. Due to the fact that chromites with a high iron content are hard, mill components ...
