Bond ball mill grindability test.The bond ball mill work index bbwi test is carried out in a standardised ball mill with a pre-defined media and ore charge.The work index calculated from the testing can be used in the design and analysis of ball mill circuits.
The bonds standard ball mill is used to determine the work index value of differ ent samples.The bond work index is defined as the kilowatt-hours per short ton required to break from infinite size to a product size of 80 passing 100 m.If the breakage characteristics of a material remain constant over all size ranges, the calcul ated work.
The ball mill is a tumbling mill that uses steel balls as the grinding media.The length of the cylindrical shell is usually 11.5 times the shell diameter figure 8.11.The feed can be dry, with less than 3 moisture to minimize ball coating, or slurry containing 2040 water by weight.

A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. A ball mill works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
Crusher impactor bond work index bond work index crusher Bond Work Index FormulaEquation See this useful summary Table of Bond Work Index by Minerals 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.
Bond (1961) also observed that the Work Index parameter is influenced by the grinding product size and attributed those variations to the natural heterogeneities of the ore. Among the correction factors proposed by Rowland (1983) for the operating Wi is the EF7, which is.
