Analysis of ice fragmentation process from measured particle size distributions of crushed ice
AbstractCrushing of ice has been studied as a general fragmentation process of a bittle material. Analysis of four ice crushing experiments shows that most of the size distributions of the crushed ice are more accurately represented by the Weibull distribution than by the power law model. This manifests against fractal size distribution. Based on the measured size distributions, together with observations from the experiments, it is proposed that the ice fragmentation events analysed can be characterised as a three stage process. In the first stage a propagating crack forms an ice flake. In the second stage, this flake breaks into a group of ice fragments. This is called a single fracture or an instantaneous break-up. In the third stage this group of fragments is loaded further and broken into smaller particles. This is called comminution.
