“…Due to the fact that it does not show chemical changes under heat and pressure, very low solubility in water and acids, with lack of magnetic properties, and cost-effective, the use in various industries has gradually increased. In the literature, there are many studies conducted and approved by the effect of the media size [1][2][3][4][5][6][7][8].…”

This study investigates the effects of the design of high-density zircon (ZrO 2) grinding media (1-3 mm) on dry grinding of barite (BaSO 4 , d 50 = 2.83 µm) in a vertical stirred media mill. Grinding experiments were carried out by using different proportions of finer grinding media (20 wt.%, 40 wt.% and 80 wt.%) and different size ratio of finer-coarser media (0.5 and 0.67). Besides, the surface areas (S bw, m 2 /kg) of grinding media on grinding performance were investigated. If the best two experimental results are compared, it is found that the S bw of the bimodal and monosized media are very close together. The experimental results were evaluated based on the product particle size (d 50 , d 90), and the geometric standard deviation of barite particles (d 84 /d 16). The findings showed that the finer grinding media alone was not very effective.

Effects of suspension pH on stability and surface properties of alumina and silica nanosuspension were investigated. Nanosuspensions of alumina and silica used in the present study were produced by wet grinding in stirred media mill. The electrostatic stabilization of two types of nanosuspension was conducted by zeta potential and turbiscan analysis as a function of pH. The long term stability analysis of alumina and silica nanosuspension was investigated using an optical analyzer. It was observed that particles gradually aggregated and settled with storage time and can be easily redispersed by mere shaking of suspensions under desirable pH conditions. Transmission electron microscopy images obtained at different suspension pH for both alumina and silica nanoparticles shows that the state of aggregation is highly dependent on pH and found to affect particles morphology.

“…Nowadays, the necessity for so-called submicron particles and nanoparticles sizes keeps on rising in industries such as paints, ceramics, water proofing materials, mining with a developing technology. Researchers have studied several strategies to achieve better submicron and nano grinding performance (Cho et al, 2009;Kumar et al, 2010;Vital et al, 2001;Yokoyama and Huang et al, 2005;Patel et al, 2014). The product size characteristics of mills are mostly affected by media size (Mankosa et al, 1989;Kwade et al, 1996;Patel et al, 2014;Bel Fadhel and Frances, 2001; Wang and Forssberg, 2007).…”

This study aimed to conduct systematic research on the design of high-density zircon (ZrO2) grinding media (0.2-1 mm) in a laboratory-scale media mill (750 ml) for wet grinding of calcite (CaCO3, d50= 5.4 µm). Sub-micron grinding experiments were carried out by using different amounts of finer grinding media (25%, 50% and 75%) and different size ratio of finer-coarser media (0.2 and 0.5). Besides, the surface areas (Sbw, m 2 /kg) of grinding media on grinding performance were investigated. If the best experimental results are compared (M1 and M4), it is found that the Sbw of the bimodal media (M4) is 75% larger compared to that of monosized media (M1). The experimental results were analyzed based on product size (d50, d80), cumulative undersize curves and specific surface area (SW, m 2 /g). The findings showed that only the finer grinding media was not very effective at 600 rpm.
