Bond S Work Index Ball Mill Manufactuering Design

The fc bond work index test ball mill was designed by f c bond for use in determining the bond index a measure of grindability and power required for grinding applications the fc bond mills are used in laboratories throughout the world a copy of fred c bonds method of crushing and grinding for determination of the bond index is included with each mill

Ball mill design requires a bond work index bwi for ball mills at the correct passing size sag mill design requires an appropriate sag test for example spi chapter 5 flotation design needs a valid measure of kinetics for each sample including the maximum attainable recovery and rate constants for each mineral chapter 12

The grinding jar for the bond index rod mill is 12 x 24 in size and has a waveshaped design at least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill the rod mill work index rwi is used for particle size determination in a size range from 25 mm down to 21 mm whereas ball mill work

Similar to a comparative work index this test is an open circuit dry batch grindability test run in the standard bond ball mill for a set time it can be used at mesh sizes from 65 to 200 mesh normally 100 mesh the test requires calibration against the standard bond ball mill work index test to estimate the work index

This grindability test or bond ball mill work index procedure is used to determine the bond work index of minus six mesh or finer feed ore samples these equation application methods are used to process 12 ore samples in a ball mill using a standard ball charge below describes in general terms the bond work index procedure used by a professional metallurgical testing laboratory if you
