Levin Grindability Index Test Method & Procedure

Grindability Index Test Method & Procedure. IsaMills. The Levin test appears to be underused for sizing regrind ball mills. Examples of the results are shown in Table 6. The requirement of 20-30 kg may be a prohibitive factor. The Levin test is a modified Bond Ball test, but makes use of finer screen sizes, and finer feed sizing.
