Sino Grinding Grinding Media

Small grinding media has a larger grinding surface area generally chosen to help make smaller ore smaller. In some cases, we find ourselves adjusting the ball size by the millimeter to approach optimization. Our knowledge and control of the ball’s design and manufacturing allows the flexibility to make such changes.
