IMPACT ENERGY CALCULATION PER UNIT MASS FOR A HORIZONTAL SHAFT CRUSHER. The Basic Assumptions made here: 1. Rotor mass is much greater than mass of single particles in the feed 2. Before impact, linear velocity of the crushing bar is much more important than the particle velocity. Hence KE of particles is negligible.
