The simple Hogg and Fuerstenau model serves such purpose well ( see Spreadsheet Mill Power _ Ball Mills ) . Then the traditional Grinding Media Consumption Indicators may be obtained from the expressions : [ 4000 k d W b ] W t = _____ d R [ 1 ( d S /d R ) 4 ] where d S represents the average size of the metal scrap being rejected by the mill .
