Rock Crushing Theory and Formula using Kick & Rittingers Law
Kick’s law is: “The energy required for producing analogous changes of configuration of geometrically similar bodies of equal technological state varies as the volumes or weights of these bodies.” In other words, the energy expended is porportional to the volume reduction, instead of the diameter reduction.

Bond Work Index - an overview | ScienceDirect Topics
In a study on crushing and grinding, fracture toughness has been taken as a key index similar to the Bond Work Index. Due to many cracks dealt with, rock fragmentation is a very complicated and difficult fracture problem.

terms. The index is defined as the energy required to crush from infinite size down to 100 µm, hence the 10 inside the brackets. Bonds Work Index values, in kWh per short ton: i.e. 2000 lbs or 907 kg, roughly follow the Mohs scale of hardness, see Table 11.1. In Summary, Kicks law is better for larger particles and Rittingers

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

Comminution - Wikipedia
Bonds law, which assumes that the total work useful in breakage is inversely proportional to the square root of the diameter of the product particles, [implying] theoretically that the work input varies as the length of the new cracks made in breakage.
Chemical Engineering Stop: Rittinger’s and Kick’s laws
May 14, 2010 · Rittingers law states that work required in crushing is proportional to the new surface created. In other words, crushing efficiency is constant and for a given machine and feed material is independent of the sizes of feed and product. Rittinger’s law is written as- P/ ṁ = Kr(1/Dsb – 1/Dsa)
QUICK METHOD FOR BOND WORK INDEXAPPROXIMATE …
Abstract: The Bond work index is a measure of ore resistance to crushing and grinding and is determined using the Bond grindability test. Its value constitutes ore characteristic and is used for industrial comminution plants designing.

* Bond F. C., “Crushing Tests by Pressure and Impact”, Trans AIME, Vol 169, 1947, pp 58-66. Bond Rod Mill Grindability Test. The test determines the Bond Rod Mill Work Index which is used with Bond’s Third Theory of Comminution to calculate net power requirements when sizing ball mills*. Various correction factors may have to be applied.
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.
