Bond work index bwi hardgrove grindability index hgi tests for biomass coal bwi can predict the potential for mill choking of biomass in a tube and ball mill hgi is a poor method of predicting grindability of biomass in vertical spindle mills pellets should be composed of predensified particles close to the target size
Bond ball mill grindability test the bond ball mill work index bbwi test is carried out in a standardised ball mill with a predefined media and ore charge 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
For overflow ball mills the charge should not exceed 45 of the mill volume for grate discharge mills the charge should occupy about 50 of the mill volume bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge he and the radius of the mill r ie
