  Impact fragmentation is the underlying principle of comminution milling of
dry, bulk solids. Unfortunately the outcome of the fragmentation process is
more or less determined by the dimensionality of the impactor and its impact
velocity. Since fragmentation is dominated by interfering shock waves,
manipulating traveling shock waves and adding energy to the system during its
fragmentation could be a promising approach to manipulate fragment mass
distributions and energy input. In a former study we explored mechanisms in
impact fragmentation of spheres, using a three-dimensional Discrete Element
Model (DEM). This work is focused on studying how single spheres fragment when
impacted on a planar vibrating target.
