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 respect of traditional Bond method.
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.
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 212µm. Abrasion Index Test
