The conditions for performing the test and initial sample size are precisely defined within Bond’s standard test. The procedure for the determination of the Bond work index for finer samples was presented in this paper. These finer samples are usually seen as a problem for practitioners who work on the design and optimization of a plant.enFiner SamplesBond Work IndexGrindabilityconferenceObject
