The Bond Abrasion Test determines the Abrasion Index, which is used to determine steel media and liner wear in crushers, rod mills, and ball mills. Bond developed the following correlations based on the wear rate in pounds of metal wear/kWh of energy used in the comminution process.
Bond Ball Mill Grindability Test. The Bond Ball Mill Work Index (BBWi) test is carried out in a standardised ball mill with a pre-defined media and ore charge. The Work Index calculated from the testing can be used in the design and analysis of ball mill circuits. The test requires a minimum of 10kg of sample that has been stage-crushed to ...
A New Approach to the Calculation of Work Index and the . factors have been adapted by Bond [5] The present work is an effort to show that the devia- tion of the W i value is due to the assumption that the ex-ponent n is equal to 0 5 It also indicates a different method to treat the experimental data by first calculating the actual value of the exponent n and then use this op- timum value to

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 ...

Compared to the other two test runs, the value obtained for the first run (.064 Ib/ton P2O5 fed) is extremely high. This irregularity is unexplainable, except for the possibility that the sample for run 1 was con- taminated. Scrubber efficiency was calculated and ranged for 93.0% to 98.7%. A complete summary of the test results are tabulated.

8/25/2016· Relation of Bond rod mill work index and crushing work index. Similar to the ball mill work index, the rod mill work index is a tumbling test that includes both attrition and abrasion breakage mechanisms. Unlike the ball mill work index, the size of the feed to a rod mill test (10 mm–12 mm) is closer to the size of the crushing test.
