Study of the Effect of the Mineral Feed Size Distribution on a …
THEORETICAL SECTION The selection and breakage functions are the main components of the batch population balance (PBM) equation. Breakage function is determined by a series of grinding tests, whereas the selection function is usually back-calculated or directly estimated from energy studies. The breakage rate is the key parameter for PBM approach. So far, several different …
