Ball milling technique, using mechanical alloying and mechanical milling approaches were proposed to the word wide in the 8th decade of the last century for preparing a wide spectrum of powder materials and their alloys. In fact, ball milling process is not new and dates back to more than 150 years.

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

For ball milling, powder and agate balls (1 mm), in a volume ratio of 4:1, were placed into an agate grinding bowl (50 mL). The samples were then ground by the agate balls at 450 rpm and the micronized samples were collected at 20, 60, and 120 min. Samples without ball milling (0 min) were used as the control.
