Among the above equations, the Bond's Law is commonly used to predict the size-reduction energy in ball/rod milling. The respective law can be written by setting m = 1.5, and integrating Eq. : (2) E (k W h / t) =-C ∫ f 80 p 80 1 x 1.5 d x = C 1 (1 p 80-1 f 80) Where p 80 and f 80 are 80% passing sizes (µm) of the mill product and feed ...
