  • Ball Millan overview ScienceDirect Topics

    Ball mills give a controlled final grind and produce flotation feed of a uniform size. 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.

    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
