[email protected]2020. 8. 22.· I need to understand how do I use the selection, breakage and appearance function equations in predicting the particle size distribution in the mill discharge given the ore characteristics and mill feed particle size distribution? I need to understand it using an actual example with numbers.
Get A QuoteSeveral important, fundamental aspects of the grinding behaviour of mineral systems are addressed. The Levenberg-Marquardt algorithm for systems of constrained non-linear equations was used to solve the steady-state and dynamic population balance model (PBM) grinding equations to obtain the mill matrices and grinding selection and breakage rate functions, respectively.
