Estimation methodology for Bond ball mill work index

2023/10/1 To determine the ball mill work index of the samples (Table 1), around 10 to 17 kg of ore was required for the particle size crushed to −3.35 mm (Amtech, 2006). The 700 cm 3 ore sample weight is fed to the Bond mill at a −3.35 mm size range. The test was started with an arbitrarily chosen number for mill revolutions (N = 50, 100, 150).

Bond Work Index Formula-Equation - 911Metallurgist

2013/7/15 See this useful summary Table of Bond Work Index by Minerals. For any circuit, whether a crushing circuit, a rod mill, or a closed ball mill circuit, the Work Index always means the equivalent amount of energy to reduce one ton of the ore from a very large size to 100 um. The sample was received crushed appropriately for the ball mill test.

One of them is the Hardgrove index, associated mainly with vertical spindle mills and the other is Bond's grindability, associated with tumbling mills [2]. Bond's grindability can be empirically related to the energy required for comminution and thus is useful for the design and selection of crushing and grinding equipment [3].
