(c) Laboratory constraints on dynamic fragmentation. Experimental studies of dynamic rock fragmentation have been conducted primarily using the split Hopkinson pressure bar (SHPB), a device by which rock samples are loaded by a transient uniaxial compressive pulse under strain rates between 10 1 and 10 3 s −1 [].Motivated by the observations of pulverized rocks along the San Andreas Fault ...

This paper shows how the efficiencies of size-reduction processes depend on the mode of particle constraint and energy transfer within the comminution device: namely, whether the process consists of single-particle loading, confined-particle-bed comminution or loose- (unconstrained-) particle grinding. The relative efficiency of single-particle comminution, ball mill grinding and particle-bed ...

A new method is proposed for measuring the grindability of solids and the energy efficiency of grinding mills. The method is based on a similarity law of fracture mechanics for elastic materials in conjunction with the self-preserving character of the size distributions formed when feed particles are comminuted individually in compression.

Our analysis of compressive loading is motivated by the observation of a "grind limit" below which the particle size cannot be reduced in commercial crushing and grinding processes [Prasher, 1987]. Particles smaller than the grind limit are observed to deform plastically, changing their shape rather than fragmenting into smaller particles.
