The Role of Particle Shape in Size Analysis and the Evaluation of Comminution Processes

Grinding Kinetics of Slag and Effect of Final Particle Size on the Compressive Strength of Alkali Activated Materials

“…At this stage, it is seen that particles are distinct and no agglomeration is observed. The evolution of particle morphology during grinding has been investigated in previous studies which reported that the type of material being ground, the mill type, as well as the mode of breakage may have a large impact on the shape of particles produced [56][57][58].…”

Issues in Particle Size Analysis

“…The size assigned is interpreted as a volume diameter and is usually larger than the true value, especially for flattened particles. The result is that light scattering systems typically report size distributions that are coarser than those obtained by other methods [7].…”

“…On the other hand, the cumulative form tends to obscure fine detail in the distribution, while graphical presentation of the incremental form offers a clearer picture of the distribution of sizes. It should be noted that the incremental distribution (qr)i is not a direct estimate of the density function qr(x), which can be approximated by (7) in which ∆xi is the size interval width, which typically is arranged to vary with size. Direct experimental determination of the density function is rarely practical.…”

“…Resolution is particularly important in the analysis of narrow size distributions, low resolution invariably leading to an apparent broadening of the distribution [7]. Precise description of the "tails" of the distribution is critical to some applications.…”

“…Rosen and Hulburt, 1970, Novak and Thompson, 1986, Ferreira et al, 1993, Hogg et al, 2004. Hence, it certainly would be preferable to repeat particle sizing using techniques that account for any shape effects.…”
