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.

Get PriceThese can be related to the Hukki relationship between particle size and the energy required to break the particles. In stirred mills, the Hukki relationship does not apply and instead, experimentation has to be performed to determine any relationship.
