1. The hardness of rocks in crushing is sufficiently characterized by a complex index (the reduced work of fracture), including the specific works of fracture by impact and by abrasion (milling). 2. The closest correlative between the productivity of the “Kaskad” mill and the reduced work of fracture corresponds to the expression of the reduced work of fracture as the sum A′=A1+ωA2

The rock strength coefficient FN is graphically determined from the curve (FΝ, Ν) and corresponds to the minimum value of the curve. This minimum value of FN is, by definition, the impact rock strength coefficient (FN), as representing the optimum specific crushing energy (minimum impact energy per unit volume of -0.5 mm material).

However, by increasing the hardness of a wear liner you also increase its brittleness. A more brittle alloy is more vulnerable to cracking under high impact. An alloy with a slightly lower manganese content (around 13-14%) will be more ductile and durable, and can therefore absorb more hits without cracking.

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 represented by the product – the feed.
