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 kWht 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 revolution, G, and ...

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, timeconsuming and requires trained operating personnel and therefore is subjected to errors.
expressed in appropriate units. In Bonds equation, if L is expressed in microns, this defines E i and Bond calls this the Work Index. The greatest use of these equations is in making comparisons between power requirements for various degrees of reduction. EXAMPLE 11.1. Grinding of sugar

Bond Rod Mill Grindability Test. Grinding Solutions can carry out Bond Rod Mill Work Index tests to determine the energy requirements for milling ore in a rod mill. The test requires a minimum of 20kg of -12.5mm material. Closing screen sizes typically range from 4.75mm to 212 m.
The work index Wi was defined by F. Bond as the specific energy kWhton required to reduce a particulate material from infinite grain size to 100 microns. The calculation is based on the size-energy relationship e1,2C.1x2n1x1n , 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 ...
A bond is an abrasive material used to held abrasive particles together. The bonding material does not cut during the grinding operations. Its main function is to hold the grains together with varying degrees of strength. The different standard grinding wheel bonds are vitrified, resinoid, silicate, shellac, rubber, and
