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′=A 1 +ωA 2 ′, where ω=1–10.
