Rock Crushing Theory and Formula using Kick & Rittingers Law
Rittinger’s theory and law of the energy expended in crushing of rock is that the work of crushing is proportional to the reduction in diameter; or, as I have more fully expressed it:
Chemical Engineering Stop: Bond’s law
May 14, 2010 · 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.
Rittinger and Kicks Laws of Crushing
Either in pushing (or pulling) back the crushing faces, or, in accordance with a more universal law of nature, attacking the weaker part of the organization and completing the breaks upon the parts that have increased load put upon them by breaks alongside them.

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- …
11 Crushing and classification - particles.org.uk
11.2 Crushing laws All the common basic equations relating energy requirement for comminution can be derived from a single ordinary differential equation kLm L E =− d d (11.2) where E is power, L is particle dimension (diameter), k is a constant and m takes one of three values depending on the particle size: -2, -1.5 or -1.
Fred Chester Bond - Wikipedia
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.
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.

* 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.

Note that the definition of particle size in Bonds law is different: D80= Particle size such that 80% by weight of the sample is smaller than it. Bonds law is often written in terms of the work index (Wi) as, Where the work index is defined as the energy required per unit mass in kWh/ton to reduce

size reduction circuits (Charles, 1957). However Bond’s Third Law can be reasonably applied to the range in which ball/rod mills operate in. In spite of the empirical basis of Bond’s theory, it is the most widely used method for the sizing of ball/rod mills and has become more likely a standard. The general form of Bond’s equation is as ...
