evaluation of bond ing inde at mill processing

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 stagecrushed to 100 passing size of 335 mm Any screen size below 600µm can be used for the testwork depending on your requirements Bond Rod Mill Grindability Test
