NS	0.13	0.23	0.76	5.85	0.54	2.64	0.5632
DS	0.16	0.32	0.71	4.44	0.90	2.64	0.5687
FS	0.13	0.22	0.80	6.15	0.47	2.62	0.5894

Note. C_u = d₆₀/d₁₀; C_c = (d₃₀)²/(d₆₀ ∗ d₁₀). is the sphericity of the particles, describing how close the particle comes to the shape of a sphere. The value of S is given by [33], where is the maximum radius of the tangential circle of the particle and is the minimum radius of the circumferential circle of the particle, as shown in Figure 6.
