Applications of Open Type Sand Mills

Our Open Type Sand Mills are widely used for fine grinding and dispersion of pigments, fillers, and binders in various industries:

Paint Industry
Automotive coatings, industrial paints, wall paints, and decorative coatings.
Ink Manufacturing
Flexographic, gravure, screen printing, and UV inks.
Chemical Industry
Pigment dispersions, water-based formulations, and solvent-based coatings.
Adhesive & Resin Industry

Open Type Sand Mill Working Principle

The Open Type Sand Mill works by circulating the pigment slurry through a grinding chamber containing high-speed rotating impeller discs. These discs create a shearing force, causing bead movement and pigment particle size reduction.

Step-by-Step Sand Mill Working Process:

  1. Raw Material Loading – Pigments, resins, and solvents are fed into the milling chamber.
  2. Grinding & Dispersion – High-speed impellers create a shearing force, breaking down pigment particles.
  3. Continuous Circulation – The material is recirculated to achieve uniform particle size.
  4. Final Output & Filtration – The milled product is filtered to remove unwanted residues.
