Energy recovery potential in comminution processes

This is indeed understandable as the new surface energy produced in comminution as described by Lowrinson 1974 is less than 1 of the energy consumed by a given mill Even if this ratio which is a definition of efficiency could be increased to 5 as is suggested by Tromans 2008 the conclusion would remain that comminution processes are very inefficient
