Comminution as a whole size reduction processes involves a sequence of crushing and grinding processes. Selection of the most appropriate comminution units and calculations of energy consumption can be estimated basing on Bond grindability ... the energy consumption of a material ground from infinite size to 100 µm. The first one is Bond's ...

Abstract. This paper reviews current testing methods for sizing autogenous and semiautogenous mills in the North American context with comments on the necessity for test work and requirements for different circuits and equipment selection.
Bond compromise • In 1951 Bond proposed, as a result of experimental work that the useful work input per ton is inversely proportional to the square root of the new surface produced, or 1 divided by d . • This represented a compromise between the surface basis of Rittinger and the diameter basis of Kick. • It was derived empirically as the result of experimental testing.

Mar 29, 2019· To calculate bond energy, start by looking up the bond energies you're working with either online or in a chemistry book. Then, multiply those bond energies by the number of individual bonds being broken, then add up all the energies on the reactant side of the equation.
Bond, 1961. Crushing and Grinding Calculations. British Chemical Engineering Crushing or grinding in closed circuit produces less fines than opencircuit operation, and causes a: to increase.
The next indicator under analysis was the Bond Work Index (W i). This parameter characterizes resistance of the material to crushing and grinding. The Bond Work Index unit is the kilowatthour per tonne, and represents the specific energy required (in kWh/t) to reduce the material from theoretically infinite feed size to 100 m [4].
