Size reduction is applied to all the ways in which solids are cut or broken into smaller pieces. Energy consumed in crushing is determined by three laws: Kick's law, Rittenger's law and Bond's law. Energy required to affect a small change "dL" in the size of the unit mass of the material is simple power function of the size. Original Description.
