Sep 24, 2021· 1. Introduction. Ball mill is one of the most commonly used mills for the crushing and grinding of mineral ore. It is generally used to grind material down to the particle size of 20 to 75 μm and can vary in size from a small batch mill up to a mill with outputs of hundreds of tonnes per hour.
Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by ...
