Optimization Of Mill Performance By Using

A Method To Determine The Ball Filling In Miduk Copper The results obtained from this work show the ball filling percentage variation is between 12 37 which is lower than mill ball filling percentage according to the designed conditions 15 in addition acquired load samplings result for mill ball filling was 13 keywords miduk copper oncentrator sag mill ball filling percentage Pdf Analysis Of Ball Mill Grinding Operation Using Mill The multisegment ball mill model developed by whiten and kavetsky has been used together with an extensive range of data from operating mills to establish the parameters of a new ball mill model Optimization Of Mill Performance By Using Mill absorbed power and ball filling degree as indicated on the graph a small variation in power could be the result of a significant variation of balls filling degree as the ball wear rate depends directly on the surface of the media charge a small variation in power will lead to an important increase of wear rate the risk of underloading or
