Rittinger and Kick's Laws of Crushing

The cycle is repeated to give 2-in., and again for 1-in. cubes. From reasoning on the lines'followed by Mr. Taggart, it would seem that the first method requires the greatest, and the repeated bisection the smallest, expenditure of energy. This indicates that, from the standpoint of work, fine crushing is best effected in several stages.
