Investigation Of Breakage Characteristics Of Low Rank

Apr 01, 2014 · The continuous hammer mill model by Austin et al. was used in this work. The equation of the fully mixed grinding model is (1) p i = f i − γ i + ∑ j = 1 i − 1 b ij γ j where (2) γ i = S i m i τ Balancing the mass in each size interval between the mill hold-up and the product for gives (3) p i = r 1 − s i m i τ

A Specific Energybased Ball Mill Model From Batch

Feb 01, 2016 · The specific energy-based ball mill model incorporates two separate functions: the selection function and discharge function.
