Impact of ball filling rate and stirrer tip speed on ...

In terms of mill operation, it was also found that a higher stirrer tip speed and ball filling rate promoted particle size reduction. However, the distribution index k was independent of the ball filling rate, which suggested that the ball filling rate had no obvious effect on the width of the PSD.

Effect of ball and feed particle size distribution on the ...

Jun 01, 2018· For this coarser feed the 50 + 20+10 mm ball diameter mix breaks the material at a faster rate compared to the other ball matches. The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate. The 10 mm ball size is unable to nip the large particle size hence the breakage rate is slower.
