For example, the figure suggests that a mill operating with an F80 of 100 μm should use 3-mm media, while a mill grinding to below 10 μm would need to use 1-mm media. To reduce a feed of 90 μ m F80 to 10 μ m P80, Figure 9 suggests that comminution be done in two stages (two Isamills or SMDs in series) for optimal efficiency.

Grinding Media | Engineered Mills, Inc.
New advances in ceramic grinding media provide many manufacturing benefits and justify the higher bead cost. Higher density, increased hardness, smoother surfaces, and uniform bead size provide long bead life and low wear on equipment. These characteristics will help when milling with smaller diameter beads, typically less than 1 mm diameter.
