Ball Rod Mill Density How Water Impacts Grinding Density, if you recall is the ratio of ore to water and is measured as a percent of solids in the water. It will control the grind in two ways. It affects retention time and helps distribute the ore throughthe mill so each piece of rock will come in contact with the surface of the rods.

The minimum bead size relates to the size and hardness of the target particles. The bead must be 20 to 40 times larger than the feed material to effect grinding. Typically this ratio falls within the range of 2040:1 (Figure 2). Example: Feed material at 50 microns. mm x 20 = mm bead. mm x 40 = mm bead.
