Effect of ball and feed particle size distribution on the ...
2018-6-1 · 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.

Ball Mills & Agitated Media Mills | Hosokawa Alpine
The fineness achieved is also determined by the size of the balls: The smaller the balls, the finer a product can be ground. The agitated media mill is a special form of ball mill, in which an agitator with stirring elements or an agitator body sets the balls in motion. Hosokawa Alpine offers a range of agitator bead mills for wet or dry grinding.
