Which can grind efficiently in a mill, c is the exponent which characterizes the ball size distribution.The condition for efficient grinding, defined by eq.7, will be fulfilled when the grain size distribution and the ball size distribution are the same, which means that the parameters of both distributions are equal in eqs.7 and 9 m c.10.
