Three types of tests are available for mill power determinations. In most cases one of two bench scale tests is adequate. First, a Jar Mill grindability test requires a 5 lb. 2 kg sample and produces a direct measured specific Hp hr/t to grind from the design feed size to the required product size. The second test, a Bond Work Index determination, results in a specific energy
