Tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on a small and large scale. Grinding elements in ball mills travel at different velocities. Therefore, collision force, direction and kinetic energy between two or more elements vary greatly within the ball charge.

3. Differences on grinding medium between wet ball mill and dry ball mill. On the grinding medium, the dry ball mill only needs to join the steel ball, while the wet ball mill needs to add liquid to participate in grinding except for steel ball. The commonly used proportion: steel ball: material: water = 4:2:1.

Planetary mill model Fritch Pulverisette P6 classic line was used for ball milling. The 10 mm diameter tungsten carbide balls each approximately weighing 8 grams were used. The milling condition was the same in both dry and wet milling with ball to powder ratio (BPR) as 15:1 and rotation speed was kept at 500 RPM.
