The ball milling process is carried out for approximately 100–150 h to obtain uniform-sized fine powder. In high-energy ball milling, vacuum or a specific gaseous atmosphere is maintained inside the chamber. High-energy mills are classified into attrition ball mills, planetary ball mills, vibrating ball mills, and low-energy tumbling mills.
Jan 17, 2019 Then 5 g portions of the powder were placed in a locally built ball mill (Forziati et al. 1950) running at 1750 rpm. The approximately one liter steel jar was chromium plated and 500 mL of stainless steel balls 0.25 in. (~ 6 mm) in diameter were employed. This is considered to be a “vibratory” ball mill in contrast to the planetary type.

A ball mill is a drum-grinding unit where balls from solid materials (steel, iron, hard alloys, ceramics, etc) are used. Most common are ball mills, where when the drum rotates and the balls rub against the inner walls, the balls are lifted until the lifting angle becomes bigger than the angle of repose. Then the grinding media are again below.
