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, …

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 …

These rods are manufactured in long lengths and can be cut quickly and be bent easily without damage. Deformed steel bars (as per IS: 1786-1985) As deformed bars are rods of steels provided with lugs, ribs or deformation on the surface of …

The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.

For comparing the standard Bond rod-mill work index and the new modeled method, work index (W i) and produced fine particles in a cycle (G i) for the four samples determined. The performed paired Student's t-test results indicated that the Standard Deviation for G i and W i obtained by the shortened method are respectively 0.50 and 0.58 in ...

A Bond Ball Mill Work Index may also be used in the simulation and optimisation of existing mill(s) and the associated grinding circuit(s). Sample requirements: A minimum of 8 kg of material crushed to nominally minus 10 mm is preferred. JKTech would stage crush the sample to minus 3.35 mm, as required for the Bond Ball Mill Work Index test feed.
