— Mechanical activation of anhydrous aluminum sulfate was performed in a planetary ball mill using hardened chromium steel vials and balls under air atmosphere. Milling was carried out at a rotation rate of 580 rpm with a powder-to-ball mass ratio of 1:15.

 — In this study, aluminum sulfate 18-hydrate [Al 2 (SO 4) 3 ·18H 2 O] particles of different sizes, which were obtained via high-energy ball-milling technology, were successfully compounded with acrylonitrile–butadiene rubber (NBR) to fabricate crosslinked rubber composites.

Well-formed aluminum nanoparticles with average particle sizes of approximately 30 nm and high specific surface areas of over 30 m 2 g −1 can be obtained using the optimal ball-milling reaction time.

 — The cementation experiments were carried out in a polyamide jar with alumina balls inside by planetary ball milling. The studied parameters were ball number (0, 4), temperature (25-55 °C)...

 — The results obtained in this study showed that ball mill-treated oil palm biomass is a suitable pretreatment method for high conversion of glucose and xylose. Oil palm biomass, namely empty fruit bunch and frond fiber, were pretreated using a …

 — Effect of ball milling (BM) of an aluminum powder on hydrogen generation through a reaction with hot water was investigated. BM increased surface area of the aluminum particles, increased crystalline imperfections in the aluminum lattice, and removed a native oxide film on surface of the particles.

 — This review examines the emergence of the technique of ball milling as a reactor technology to enable mechanical activation of zero-valent metals.

 — Ball milling was revealed to increase the accessibility of cellulose to the catalyst and disrupt the cellulose hydrogen-bonding networks, which facilitated the decomposition of cellulose.

Here we show that the ball milling pretreatment could markedly facilitate the conversion of microcrystalline cellulose to HMF by titanyl sulfate (TiOSO 4). The ball milling pretreatment remarkably decreases the degree of crystallinity of microcrystalline cellulose with a reduction of molecular weight via disrupting the hydrogen bond and ...

 — Abstract. Microscale zero-valent aluminum (mZVAl), an excellent electron donor, presents great potential in the field of water treatment. However, surface inherent oxide film impedes its development and application. High-energy ball milling is a promising approach to enhance the reactivity of mZVAl.
