  • Dispersion of Nanoparticle Clusters by Ball Milling

    A lab scale Fryma Co‐Ball mill (0.5 L volume) is used and the effects of bead fill (40–70 ) flow rate (0.1–1 kg/min) and rotor speed (7.5–18 m/s) are investigated. Specific energy is the most effective ways to correlate performance to particle size suggesting that residence time (i.e. flow rate) is the most important process parameter.
