Grinding Medium an overview ScienceDirect Topics

Jankovic [14] showed that the grinding media size must be matched to the feed size with the following observations: • Tower mill: • Finer media were more efficient for grinding fine particles. Decreasing the media size from 12 to 6.8 mm increased the size reduction while decreasing the media size further to 4.8 mm decreased the mill

Grinding Media Growth Steel

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
