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 revolution, G, and ...

granite, feldspar and quartz were tested for hardness, abrasion, compressive strength and modulus of elasticity and the bond work index of these samples were estimated. The value of Bond work index of the above samples has shown a variation from 10.8 kwh ton-1 for bauxite (high abrasion value and low compressive strength) to 20.4 kwh ton- 1
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 212µm.
1, according to Bond [2] n = 0.5 and according to Charles [3] and Stamboliadis [4], n. can take any value near these two. In the case that the initial size is infinite and the final size is 100 μm then by definition the required specific energy is called work index . W. i ,100 e W. i (2) The value of the constant .

The axial movement of the work –piece is obtained by tilting regulating wheel at (5 0 ...
Aug 24, 2013 Similar hardness to quartz (Mohs ~7). I know this is done on purpose built machines, but for a small peice can it be made to work on a small CNC mill. Currently my thoughts are to mount the stone in the bottom of a fixture with pan built in. Fill with water, and allow a diamond burr to very slowly feed into the part.
