From: Effect of ball collision direction on a wet mechanochemical reaction

Snapshots of ball motion during the wet planetary ball milling at 150 G. Left column, ϕ3 mm; middle, ϕ5 mm; right, ϕ8 mm. Ball input: (a–c) 50 g, (d–f) 80 g, and (g–i) 140 g. The line from the center of the vessel indicates the direction of the center of revolution. Water is omitted from the visualization. Visualization of the simulated data was performed using ParaView software (ver. 5.8.0).
