to ball filling variation in the mill. The results obtained from this work show the ball filling percentage variation is between 1.2– 3.7 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 1.3 .
Chat Online2021 9 16 Ball Mill Filling Ratio. Sep 04 2021 The weight of the ball in the ball mill can be estimated by an empirical formula. The formula for the filling ratio of the ball is the filling quantity of the ball = 3.14X the square radius of the radius of the ball mill X the specific gravity of the ball X the length of the ball mill X 25 1000.

The fill level inside a ball mill is a crucial parameter which needs to be monitored regularly for optimal operation of the ball mill. In this paper a vibration monitoring based method is proposed and tested for estimating the fill level inside a laboratory scale ball mill. A vibration
Chat OnlineBall milling of rye bran gave rise to similar results with the A/X ratio of the extractable AX being considerably lower 0.51 . Optimization of the ball mill treatment by varying the degree of filling of the milling jar permitted us to obtain equally high WE AX levels >70 in wheat and rye bran within a 24 h ball milling period.
