Bond Work Index an overview ScienceDirect Topics. The rod mill work index laboratory test is conducted by grinding an ore sample prepared to 80% passing 12.7 mm (½ inch, the original test being developed in imperial units) to a product size of approximately 1 mm (in the original and still the standard, 14 mesh; see Chapter 4 for definition of mesh), thus determining the rod mill …

The standard Bond Rod Mill Work Index test procedure is firstly to stage crush the feed to pass 12.7 mm, and size a representative sample. The test then involves a series of batch grinds in a standard Bond rod mill. A Bond rod mill is 0.305m by 0.610m, with wave liners (of a form described by Bond), which runs at 40rpm and tilts as described below.

Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture. As such, when the product is sticky, rod mills are preferred over ball mills.

To calculate Bond rod-mill work indices, the four samples were screened and the particle size distributions plotted in Fig. 2.The plot was used to find F 80 of the samples for calculations. Fig. 3, Fig. 4 show the grinding kinetics of Pb, Cu, Fe, and Mn ores in the Bond rod-mill in different test-sieves. The slopes of all lines in the figures are equal to the k value of Eq.
