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 100 passing size of 3.35 mm.
Bond work index value of these components mixtures is greater than the Bond work in-dex of harder components clinker. Oner 2000 have conducted a research of clinker and blast furnace slag mixture Bond Work Index in different mass propor-tions. He found out that these values are always lower than the Bond Index obtained
behavior can be expressed as an energy coefficient or work index.
