How it Works: Crushers Grinding Mills and Pulverizers

Where: E=Energy K K =Kick’s Constant f c =crushing strength of the material L 1 =initial length and L 2 =reduced length. Bond’s Law states that the total work input represented by a given weight of crushed product is inversely proportional to the square root of the diameter of the product particles.
