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 ...

Sino Grinding Grinding Media
2021-3-1 The size of grinding media plays a key role in overall performance of the grinding circuit. Larger grinding media has a smaller grinding surface area, but offers a heavier weight that’s generally used to break larger ore. Small grinding media has a larger grinding surface area generally chosen to help make smaller ore smaller.
