important, although secondary role, in the ball mill. Second, it assumed that the fracture strengths of particles remain unchanged throughout the process, whereas it is now recognised (Tavares and

Since October 2003, the BHP Billiton Cannington mill has operated a grinding circuit consisting of an AG mill, pebble crusher and a Vertimill which in this paper will be referred to as an AVC circuit. What is unique about this circuit is that it utilizes a Vertimill for secondary grinding rather than the conventional ball mill.

Planetary ball mills are smaller than common ball mills and mainly used in laboratories for grinding sample material down to very small sizes. A planetary ball mill consists of at least one grinding jar which is arranged eccentrically on a so-called sun wheel.

The purpose of the laboratory ball mill test was to determine the cyclone underflow grindability using different size grinding balls. A laboratory ball mill, (D x L = 0.2 x 0.26 m at 75 rpm

Single-compartment mills are of a similar design to air-swept mills, but the material is discharged mechanically by a discharge diaphragm. These mills are well-suited for finer feed materials. They are used for secondary grinding downstream of a primary grinding unit or in a combi-grinding system with a polycom high-pressure grinding roll.
