Dec 26 2017 mill geometry and speed according to bond (1954) the grinding efficiency of a mill depends on the ball mill diameter size of the media and mill speed ball mills with different length to diameter ratios for a particular power rating will produce different material retention times.
: total ball abrasion in the mill (g) ?b: each ball volume (m3) ?b: supposed ball filling percentage a r: ball abrasion rate in the mill if above calculation were done again for ?b 2% total ball abrasion will get 6096 finally the second one is not acceptable because the balls went out from the mill.
Where g (t) was the weight of media loading in the ball mill; v (v 121 m 3) represented the effective volume of ball mill; the (%) was the space-filling factor; ( 485 tm 3) represented the bulk density of media (3) the calculation of power for per ton ball medium the media addition was calculated via .
Which enables us to see how the attritor fits into the family of mills for example ball mills use large media normally 12 or larger and run at a low (10-50) rpm the other mills such as sand bead and horizontal use smaller media from 03mm to 2mm but run at a very high rpm (roughly 800-1200).
