Bond Work Index. In the 1930s through early 1950s, Bond developed a new theory of comminution that introduced an index, called the 'Bond Work Index', which relates power consumption in crushing and grinding to the feed and product size distribution. His theory and index were introduced in a widely cited 1952 journal article. Bond called his theory the "third …
The grinding is the last stage of comminution in a mineral processing plant, responsible for reducing particles in size by mechanisms of fragmentation, impact, compression, and shear. Moreover, it is one of the stages that requires greater focus due to the more energy-consuming and major investments requirements. The grinding is considered very important for the …

The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test screen undersize per …

Crushing and grindability are the parameters that characterize the resistance of raw materials to crushing. There are several procedures for determining the brittleness and grindability, and in practice, the most widely used methods are F. C. Bond (Bond, 1961).

The work index Wi was defined by F. Bond as the specific energy (kWh/ton) required to reduce a particulate material from infinite grain size to 100 microns. The calculation is based on the size-energy relationship e1,2=C.(1/x2n–1/x1n ), which for n = 0.5, x1 = ∞ and x2 =100, by definition gives e∞, 100 = Wi and consequently C=10Wi. In theory, for a given material the value found …
