Abstract The Bond work index is a measure of ore resistance to crushing and grinding and is determined using the Bond grindability test. Its value constitutes ore characteristic and is used for industrial comminution plants designing. Determining the Bond work index value is quite complicated, time-
The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic 38 measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test screen undersize per

The calculation is based on the size-energy relationship e1,2C.(1/x2n1/x1n ) , which for n 0.5, x1 and x2 100, by definition gives e, 100 Wi and consequently C10Wi. 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 the energy e.

Calculations involving Bonds work index are generally divided into steps with a different Wi determination for each size class. The low energy crushing work index laboratory test is conducted on ore specimens larger than 50 mm, determining the crushing work index ( WiC, CWi or IWi (impact work index)).

conventional crushing and grinding circuits (crusher-rod-ball mill or crusher-ball mill). By the 1970s, the application of conventional tended to be limited to relatively low capacities. circuits The majority of modern grinding circuits include a SAG mill, a ball mill and/or a combination thereof. The use of Bond

It implies that the specific energy required to crush a material, for example from 10cm down to 5cm, is the same as the energy required to
primary and secondary crushing and grinding. The final product is 80% passing 270 mesh. Bond has published a Wi for taconite of 14.87 (1961). This value is used in these base case calculations.

Several methodologies have been developed for designing crushing and grinding mills. Bonds method is widely used for predicting the energy requirement
Nov 18, 2014 The Bonds work index values increased as test sieve size decreased. 16. Bond work index is changed with the change in the test sieve size and circulating load. This must be taken into account when energy consumption is calculated according to the Bond formula. unit energy cost extra increased as circulating load decreased from 250%.
Particle shape and size are main factors influencing particle breakage. Single-particle breakage tests were conducted on irregular magnetite ore using modified drop weight impact equipment to analyze the effect of shape and size on specific breakage energy. A method to measure the effective breakage energy is presented. Ore particles with different sphericities and different
