Jun 16, 2015 Sizing a crusher can be done reliably calculated thanks to the Impact/Crushing Work Index and the testwork research done by Fred Chester Bond and his 1952 paper. According to Bond’s Third Theory of Comminution, the work/energy input is proportional to the new crack tip length created during particle breakage and equivalent to the work

The Bond low-energy impact crushing work index (more informally, the Bond crushing work index) is not as common as the Bond ball mill work index, and it is a notoriously noisy test.. The test is a 'per-specimen' test where individual specimens of prepared rock are hand-picked by the test operator and placed into the apparatus.
The Bond crushing work index test (sometimes called the "impact work index" test) is noisy, and the difference you observed is perfectly reasonable. The paper by Angove & Dunne (1997) reports a standard deviation in crushing work index tests across laboratories as 4.5. The laboratory CWi value of 27.4 (metric) is almost within 4.5 units of the

where Wi is the Bond Work Index, again in energy per unit mass terms. The index is defined as the energy required to crush from infinite size down to 100 µm, hence the 10 inside the brackets. 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.

May 14, 2010 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

Energy Required to Crush Coarse Materials according to Bond's Law calculates the energy needed to crush raw materials such that they pass through a sieve aperture of lower diameter and is represented as E = W i *((100/ d1)^0.5-(100/ d2)^0.5) or energy_per_unit_mass_of_feed = Work Index *((100/ Feed Diameter)^0.5-(100/ Output Diameter)^0.5).Work Index always means the equivalent amount of
