particle size distribution in crushing unit of cem

3.2.1. Effect of Particle Size on Particle-Size Distribution after Crushing. In the DEM simulation, 10 mm, 14 mm, 18 mm, and 22 mm balls are accelerated to 45 m/s to make their unit impact crushing energy consistent. Using statistical methods, we analyze and compare the particle-size distributions after crushing as shown in Figures 13–16.
