How Material Size Directly Affects Size Reduction

25/03/2015· Rittinger s Law — The energy required for reduction in particle size of a solid is directly proportional to the increase in surface area E = K R f c 1/L 2 1/L 1 Kick s Law — The amount of energy required to crush a given quantity of material to a specified fraction of its original size is the same regardless of the original size
