The kinetic energy loss in particle-wall impact is distributed between different mechanisms. These mechanisms were modeled using only material mechanical properties, impact conditions and particle area. With this model, the particle breakage probability (BP) was plotted in terms of the available energy to damage the particle. It was found that breakage probability is scaled well with the available energy for softer targets. Thus, a generic BP function can be derived for different types of targets. Additionally, particle fracture energy is modeled in terms of surface energy and the new exposed area. This area was evaluated using Monte-Carlo simulations. The simulation results suggest that SiC fracture energy is larger compare to quartz because of smaller surface energy. For potash, the compression energy obtained in quasi-static compression tests is found to be larger than the fracture energy in impact. But if plastic deformation and fracture is considered, it exceeds the compression energy.
