The standard Bond Ball Mill Work Index test procedure is firstly to stage crush the feed to minus 3.35mm, and size a representative sample. The test then involves a series of batch grinds in a standard Bond mill. A Bond mill is 0.305m by

Grinding in Ball Mills: Modeling and Process Control

2012710&ensp·&enspThe design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the ratio "length to diameter" and this

For any circuit, whether a crushing circuit, a rod mill, or a closed ball mill circuit, the Work Index always means the equivalent amount of energy to reduce one ton of the ore from a very large size to 100 um. The sample was received crushed appropriately for the ball mill test.

Analysis of ball mill grinding operation using mill power

With a view to developing a sound basis for the design and scaleup of ball mills, a large amount of data available in the literature were analyzed for variation of the two key mill performance parameters: power specific values of the 'absolute breakage rate of the coarsest size fraction', S *, and 'absolute rate of production of fines', F *, with some of the important operating and

According to the Bond standard procedure, the work index is determined by simulating a dry grinding in a closed circuit in the Bond ball mill to achieve 250% circulating load (Bond, 1949, 1952, 1961). The test is performed on a raw material approximately weighing 10 kg, which coarseness is 3.327 mm.
