Ball-milling exfoliation is using a planetary mill to mix and roll the balls, raw materials, and milling agents to reduce the thickness of 2D materials by shear force. For example, Lei et al. developed an effective solid-phase exfoliation for BNNS by ball milling the mixture, the BN powder and urea molecules (Figure 2a,b).

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 through-the mill so each piece of rock will come in contact with the surface of the rods.
