Understanding the mechanism: How does a ball mill work?

Components of a Ball Mill. 1. Drum: The drum is the main component of the ball mill, which houses the grinding media and the material to be milled. It is typically made of steel and is rotated at a specific speed to achieve the desired milling outcome. 2. Grinding Media: Grinding media are small metal balls that serve as the primary milling agents.
