A specific energy-based size reduction model for batch

Jan 01, 2015· 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 energy-size reduction function, which calculates the particle breakage index, t 10, according to the size-specific energy, and then calculates the full product size distribution using the t 10 –t n relationships and the mass-size balance approach.
