#### A New Approach to the Calculation of Work Index and the ...

Work Index, Potential Energy, Grinding . 1. Introduction . The size-energy relationship is generally expressed by the following Equation (1), 1,2 21 11 nn eC. x x (1) where . e. 1,2. is the specific energy required to grind a par- ticulate material from initial size . x. 1. to final size . x. 2. The parameter . C. is a constant and . n. is an exponent that ac- cording to Rittinger [1] n = 1 ...
