The Advantage of Particle Size Analysis of Cement. The angle where the particles scatter light is dependent on their size; hence, particle size information may be collected. Using a suitable scattering model, its particle size distribution may be determined by monitoring the angular dependence of such scattered light.
The mechanism of the influence of the particle size distribution of aggregate on the strength of the cemented filling material is still very blurred so far [50]. One can only point out that there may be such an optimal particle size distribution, but it involves more in-depth research and why it performs the superior material properties …
Too small of a media size or too large of one can decrease the mill efficiency, making the media size dependable on the ground particle size. That is, in the case of a particle size below 10 μm, finer media sizes were more effective, and when the media sizes were between 1.7 and 1.2 mm, efficient grinding was performed [ 24 ].
The particle size distribution is shown in Fig. 2. Based on these data, we can conclude that low-intensity milling is ineffective in reducing the Fe-Ga particle size (green and blue curves), especially in the case of 2:1 BPR. There is a bimodal particle size distribution with a weak peak around 60–70 µm and a strong peak in large particles.
When the jet mill is compared to the ball mill, the jet mill is able to grind materials to a smaller particle size (1–10 μm) with a narrower particle size distribution [5]. The fluidity of jet mill ground cement/limestone mixture and shape of cement particles have been examined [5], and it was found that after jet mill grinding, the ...

Particle size distribution In general, the most significant effect of mechanical activation is to change the PSD of materials; thus, these distributions for ground steel slag are discussed first. The PSDs of the steel slags subjected to the two grinding methods (dry- and wet-grinding) for 0.5, 1.0 and 2.0 h are shown in Fig. 2.
