Theory of Size Reduction
Most popular comminution laws are those proposed by Kick, Rittinger and Bond. Kick's Law (1885): Kick's law that can be applied to crushing states that "the work required for crushing a given quantity of material is constant for a given reduction ratio irrespective of its original size". Mathematically this law can be expressed as
