Measuring ore grindability in balls mills. The Bond Ball Mill Work Index is a measure of the resistance of the material to grinding in a ball mill. It can be used to determine the grinding power required for a given throughput of material under ball mill grinding conditions.
Procedure for determination of ball Bond work index in the
1. Introduction. A Bond Ball Mill Work Index test is a standard test for determining the ball mill work index of a sample of ore. It was developed by Fred Bond in 1952 and modified in 1961 (JKMRC CO., 2006).This index is widely used in the mineral industry for comparing the resistance of different materials to ball milling, for estimating the energy required for grinding, and for ball mill
Correction of Bond Ball Mill Work Index Test for Closing
Ore samples from Copper Mountain and New Afton mines were used for the Bond ball mill work index tests conducted at the University of British Columbias CMP laboratory. The first sample is a composite of four Copper Mountains geounit samples with similar alteration (AlbitePotassicArgilic) sampled at different pit locations and benches.
Investigating of the effect of ore work index and particle
The d80 of ore reached to 480 μm in all samples to prepare materials for ball mill grinding experiments, because d80 of plant ball mill feed in Sungun plant was 480 μm. As a base for this study, standard Bond grindability tests were initially done and Bond work index (Wi) values were calculated for
Bond Rod Mill work index, Bond Ball standard Bond Ball Mill method. Procedure for determination of ball Bond work index in the It provides the Bond Ball Mill Work Index which expresses the resistance of has been proved on samples of copper and Iron ores that are located in Iran.
