    Bond crushing law. A. Calls for relatively less energy for the smaller product particles, than does the Rittinger law. B. Is less realistic in estimating the power requirements of commercial crushers. C. States that the work required to form particle of any size from very large feed is proportional to the square root of the volume to surface ratio

  • Rock Crushing Theory and Formula using Kick & Rittinger's

    “The work done in crushing is proportional to the surface exposed by the operation; or, better expressed for this purpose, the work done on a given mass of rock is proportional to the reciprocal of the diameter of the final product, assuming that all the mass has been reduced to one exact size, which is only theoretically possible.”

  • Chemical Engineering Stop: Bond’s law

    Bond postulated that work required to form particles of size Dp from very large feed is proportional to the square root of the surface-to-volume ratio of the product, Sp/Vp. By relation Sp/Vp = 6/ɸsDp, from which it follows that P/ ṁ = Kb/ (Dp)^0.5 Where Kb is a constant that depends on the type of machine and on the material being crushed.

    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. The sample was received crushed appropriately for the ball mill test.

  • Fred Chester Bond Wikipedia

    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's Work Index values, in kWh per short ton: i.e. 2000 lbs or 907 kg, roughly follow the Moh's scale of hardness, see Table 11.1.

    The Bond work index (Bond, 1960) is based on Bond’s law, which states that the energy consumed is proportional to the 1.5 power of particle size rather than the square of Rittinger’s law. Accordingly, the energy consumed in reducing the particle size from x F to
