Ball Mill Grinding Media Size

Media to media contact for rods mills is linear rather than point to point as with balls and are much heavier. The larger feed tends to separate rods at the feed end such that larger particles are preferentially abraded. This leads to a narrower size distribution and significantly less slime compared to ball mills.

Choosing the Best Media Mill For Your Wet Grinding Application

Jul 01 2003 Figure 3 depicts the effects of media size on grinding times. From this plot it is shown that a target fineness of 80 2 microns is normally achieved in 315 minutes of recirculation milling with 1.0 to 1.4 mm grinding media. By reducing the media diameter to 0.6 to 0.8 mm after 90 minutes the target grind is achieved in only 150 minutes.
