mill grinding rate over the material's grindability as measured in the lab. Mill percent solids optimization has thusly been achieved (McIvor et al., 2000). For media sizing, maximizing the mill grinding rate on a given ore is equivalent to maximizing the mill grinding efficiency. Ores of different grindability will be part of the discussion.

Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns.; The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns.; The Center-Periphery Discharge mill has feed reporting from both ends and the product …

The ball milling method enjoys greater popularity in the industry as it is much easier to be controlled. Ball milling methods are usually divided into dry ball milling (DBM) and wet ball milling (WBM). DBM is mainly carried out in the environment of gas atmosphere, e.g., argon ambient. WBM is mainly conducted in liquid environment, e.g., ethanol.

Conical Ball Mills Used wet or dry, closed or open circuit, conical ball mills provide a classifying action within the body of the mill due to particles of greater size tending to reside at a point of greater diameter. This characteristic delivers increased efficiency and lower power consumption. Conical mills may also be air-swept when run dry.
