  • Using Abrasion Index for calculating Steel Balls and mill

    Are the old AllisChalmers Abrasion Index and calculations for Steel Balls and liners consumption still valid? The AllisChalmers Standard Abrasion test has been used for several decades to calculate steel consumption Current advances in alloys composition and on heat treatment may be producing steel balls and liners that would last longerA few years ago, McGill University in Canada developed a new and more accurate test methodology for predicting steel media consumption This test (Steel Media Wear Test) is licensed and currently being offered commercially by JKTech The test also has the advantage that it produces estimates of thePredicting Steel Media Consumption Grinding

  • SAG Mill Ball Size Evaluator | Evaluation Factors

    SAG Ball consumption is “average” at 400 g/t while Ball Mill grinding media (3″ balls) usage in 550 g/t Yet, you add steel and nothing seems to happen, tonnage is not noticeably improved You need more tonnage and could actually use a larger/coarser transfer size from the SAG to Ball MillCalculate Top Ball Size of Grinding Media FRED C BOND Equation & Method Previous Next Although it was developed nearly 50 years ago, Bond ‘s method is still useful for calculating necessary mill sizes and power consumption for ball and rod millsCalculate Top Ball Size of Grinding Media Equation &

  • Calculate and Select Ball Mill Ball Size for Optimum Grinding

    In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do Often, the ball used in ball mills is oversize “just in case” Well, this safety factor can cost you much in recovery and/or mill liner wear and tearsteel balls in a ball mill, or large lumps of ore in an autogenous mill or a mixture in a semiautogenous mill, as well as the slurry that makes up the operating charge Let Jt be the fraction of the mill volume that is occupied by the total charge, Jb the fraction of the mill volume that is occupied by steel balls and E the voidage of the ballsTECHNICAL NOTES 8 GRINDING R P King
