Ball milling is a popular grinding method. The wet ball milling process involves a drum filled with grinding media, like metal balls, and the material to be ground. The drum's rotation causes the media to grind the material into finer particles. On the other hand, the dry ball milling process avoids any liquid, relying solely on the drum's ...
