### F. C. Bond, "Crushing and Grinding Calculations," British …

The calculation is based on the size-energy relationship e1,2=C.(1/x2n–1/x1n ), which for n = 0.5, x1 = ∞ and x2 =100, by definition gives e∞, 100 = Wi and consequently C=10Wi. In theory, for a given material the value found for Wi.should be constant regardless of the measured sizes x1 and x2 used to calculate the constant C by measuring ...
