Calculating breakage parameters of a batch vertical stirred mill

The paper discusses the outcome of a series of test work carried out in a screw type batch vertical stirred mill to evaluate the effect of experimental conditions on the product particle size distribution and generation of fines. A time-based population balance model has been utilized to develop mill selection and breakage function for different operating conditions. A systematic variation in both selection and breakage functions of the population balance model with changes in process conditions are fitted through regression models.
