In a hammer mill designed for fine grinding [7], it . Fracture by impact. When a particle of a given size is impacted at a relative velocity v, the total specific kinetic energy (J/kg) at the instant of impact is E=v 2 /2. As the particle is compressed and slows down (with respect to the hammer), kinetic energy is converted to strain energy.
