# Bimodal Size Distributions in Grinding and Attrition

Bimodal Size Distributions in Grinding and Attrition

This Demonstration simulates the varying particle size distributions during the disintegration of particulates. It enables visualization of the difference when either particle shattering or surface attrition dominates the disintegration process or when the two play a comparable role. The actual scenario is determined by the relative time scale of the size reduction of the coarse fraction and that of the fines formation. The Demonstration is based on both fractions having normal size distributions and hence not all plots generated by the Demonstration correspond to real-life particulates.
