  • Pdf Spreadsheet Based Simulation Of Closed Ball Milling

    two of the three data sets were used to calibrate the ball mill and hydrocyclone models. At first step, measured data were adjusted using nor-bal mass balancing and data reconciliation software then, using adjusted data the selection function of tube ball mills was estimated by ngotc softwarethe attritors design accounts for much of the difference: conventional ball mills turn the entire drum or tank containing the media and the material, while attritors stir the media in a stationary tank with a shaft and attached arms or discs resulting in a more efficient use of energy for the milling process.
