Size-energy relationship exponents in comminution

The generalized size-energy relationship e = W 1 r p f - 1 r f f is the sum of two terms, with the product term being dominant, as r p is smaller than r f. Isolating this dominant term gives e = W r p f 1 - r p f r f f. The logarithm of this expression is written as Ln e = - f L n r p + L n W + L n 1 - r p f r f f which is approximately Ln e ...
