Fast test method for the determination of the grindability ...

Generally Bond work index for mill dimensioning and controlling is measured by grinding a feed material of <3.36 mm particle size under standardized conditions in a so-called Bond mill (D × L = 305 mm × 305 mm).

Bond Work Index Tests - Grinding Solutions Ltd

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 test requires a minimum of 10kg of sample that has been stage-crushed to passing size of <3.35 mm.

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.

CORRELATION BETWEEN BOND WORK INDEX AND .

The Bond's 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 µm. If the breakage characteristics of a material remain constant over all size ranges, the calcul ated work index would be expected to remain constant since it indicates the .

Additionally while techniques like the Bond Work Index and "scale up factors" are useful for coarse grinding, they can significantly underestimate grinding needs below 100 microns. Similarly Tower Mill laboratory tests typically use much finer media than can be used in full scale operation and testwork is done in "batch" mode.
