Ball size distribution inside an industrial mill was analysed in terms of particle breakage in ball mill (the Size Mass Balance Model Austin et al Cement Mill Notebook Scribd
A ball mill grinding circuit is a nonlinear process characterised by significant process interaction as a typical manipulated variable interacts with multiple controlled variables To facilitate an accurate representation of the complex process dynamics a rigorous ball mill grinding circuit is simulated The dynamic model is used in its entirety
Given the mass and component balance equations F = C + R Ff = Cc + Rr Mass yield (Y) can be solved as a function of the stream assays which yields the two product formula R = F C Ff = Cc + r (F – C) Mass Yield Formula Example
