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.

Get priceBond 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 theorySizing 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 represented by the product – the feed.
