 · The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account.

ball mill for veolia process. The Attritor's design accounts for much of the difference: conventional ball mills turn the entire drum or tank containing the media and the material, while Attritors stir the media in a stationary tank with a shaft and attached arms or discs resulting in a more efficient use of energy for the milling process.

A ball mill constitutes a rotating, horizontal steel cylinder, often called the drum, which contains steel or ceramic balls of 25–150 mm in diameter. It can also be operated under dry or wet conditions. 1,2. Relationship between rotation speed and impact/shear forces. At low speeds or when small balls are used, shear forces predominate.
