Sand Mill Selection Guide: Disc, Rod-Pin, Turbine or Basket?
10/4/2026
The sand mill is the core wet-grinding machine for coatings, inks, color pastes and new materials. Wrong selection causes unqualified fineness, insufficient capacity or excessive energy use, so selection must be based on systematic process evaluation.
Select by Target Fineness
By target fineness: for conventional 5-25μm, disc-type mills (such as the TSM sealed horizontal mill) offer the best value; for sub-micron or nano-grade fineness, choose rod-pin (TDB) or turbine (TTN) nano sand mills with high energy density and narrow distribution.
Select by Viscosity and Process Continuity
By viscosity and continuity: high-viscosity pastes favor machines with strong pumping or circulation grinding; for small-batch multi-variety production with frequent color changes, basket mills (LS) need no piping and clean easily; for large continuous output, high-flow models (TDP) come first.
Grinding Media and Cooling Capacity Matter Too
Grinding media (zirconia beads) are equally critical: bead size must match target fineness (0.3-1.0mm for nano grinding), with loading typically 60%-80% of chamber volume. When selecting, evaluate media options and cooling capacity together, and run process trials when necessary.
