Rapid determination of Bond rod-mill work index by

Jan 01, 2013 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.

Simulating the Bond rod mill grindability test ScienceDirect

Jan 01, 2012 Highlights A simplified procedure is proposed to calculate the Bond rod mill work index. It accounts for the accelerated breakage rates of coarse particle in the rod mill. It uses about 1/5th of the sample volume when compared to the standard test. It is based on simulation of the test from data collected in batch tests. It predicted the Bond rod mill work index with less than 1 kWh/t and 10%
