Each ball feedercounter system is designed to accept a narrow range of ball diameters and should not be used to charge balls of mixed sizes weightbased counter the autocharge systems weightbased counter is suitable for all ball diameters but is particularly applicable to smaller ball sizes 5080 mm including ball recharge practice
Oct 01 2000 summarising the magotteaux automatic ball charger can optimise ball mill grinding by maintaining the charge of the ball mill within 50 kg of the optimum level at all times industrial experience has proven that the abc can be operated with minimum operator effort requiring only periodic filling of the ball storage hopper
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
To define a balanced charge distribution let us take an example of mill first chamber with 28 charge fill with quantity 403 mt where 90 dia mm ball is used as max size change in ball
The optimal ball diameter in a mill of the equation for determining the optimal ball diameter depending on the grain then the determination of the optimal ball charge model in a mill 2 grinding samples was equal to the volume of the interspaces of balls and the interstitial read more
