Figure 4.
Panel A plots cumulative particle size in per cent against particle size in millimetres for C E M one. The alpha one and alpha two curves remain close at smaller particle sizes. Both increase gradually before rising sharply at larger particle sizes. Alpha two finishes above alpha one. Panel B plots the same variables for C E M three. The alpha two curve remains above alpha one throughout. Both curves increase gradually and then rise steeply at larger particle sizes. Alpha two approaches 100 per cent, while alpha one ends lower.Particle size distribution of the output materials: (a) CEM I; (b) CEM III for each angle (α1 = 90° and α2 = 85°)
