  • The Third Theory Of ComminutionOneMine

    The Rittinger theory is the older and more widely accepted. In its first form as stated by P. R. Rittinger it postulates that the useful work done in crushing and grinding is directly proportional to the new surface area produced and hence inversely proportional to the product diameter.

    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 for Wi

    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 revolution G and
