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. In some cases, we find ourselves adjusting the ball size by the millimeter .

Grinding of minerals like TiO 2 or CaCO 3 to the right particle size distribution (including narrow distribution and very small D50) is possible with the correct selection of the ER120 bead size. The smooth surface of ER120 limits energy losses due to the reduced bead-to-bead friction, making it more cost effective than natural sand, for instance.
