Bonds Work Index Ball Mills Insmart Systems The bonds ballmill work index is a measure of the resistance of the material to grinding in a ball mill this index is widely used in the industry for comparing the resistance of different materials to ball milling for estimating the energy required for grinding and for ball mill scaleupNumerically, the work index is the energy required in kwh/t to reduce a given material from theoretically infinite feed size to 80% passing 100 microns The work index of a particular material is determined in the laboratory by conducting the standard Bond grindability test Bond developed separate tests for the rod mill and the ball millDetermination Of The Bond Work Index Using An Ordinary Bonds Crushing Law And Work Index Kaseo Heavy Work index for iron ball mill rock quarry crusher for sale bond crushing law in ball mill rock quarry lake for sale bond crushing law in ball mill rock quarry lake for sale have been developed and adopted in the hardrock 111 vi appendix c standard bond ball mill work index data circuit consisting of multiplestage crushing followed by rod and bonds ball mill work index bildungsgewitterde

The ball mill work index laboratory test is conducted by grinding an ore sample prepared to 100 passing 336 mm 6 mesh to product size in the range of 45150 m 325100 mesh, thus determining the ball mill work index Wi B or BWi The work index calculations across a narrow size range are conducted using the appropriate laboratory work index determination for the material size of This is because work index frequently changes as a function of the product size in comminution If target grind size during a project is changed, or if the test is run at the wrong product size, then it is necessarily to provide a correction The goal of this work is to create an equation to adjust a Bond ball mill work index from one P 80 basisCorrection of Bond Ball Mill Work Index Test for Closing A Bond Work index mill ball charge and closing screen product size distributions for grinding crystalline grains Int J Miner Process , 165 ( 2017 ) , pp 8 14 , 101016/jminpro201705011A new approach to the calculation of bond work index for

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) get price Bond Test WI’s (kWh/t): Rod Mill: Ball Mill: 95 kWh/t8 9 kWh/t Bond Standard Circuit Work Index: Assume the rod mill Work Index of 95 applies from the actual rod mill feed sizeof 19,300 mµ (although some of this work might ideally be done by crushers to achieve a rod mill GMSG GUIDELINE: DETERMINING THE BOND
