Spray Dried Kaolin – The Free-Flowing Solution
Spray Dried Kaolin is a specially engineered material produced by atomizing a high-solids kaolin slurry into a stream of hot air. As moisture evaporates instantly, it forms uniform micro-beads instead of fine powder.
This advanced physical form eliminates common challenges like clumping, dusting, and inconsistent flow, making it ideal for automated and high-performance industrial processes.
Key Performance Properties
- Excellent Flowability: The spherical shape allows the material to flow easily through silos, hoppers, and pneumatic conveying systems.
- Low Dusting: Larger, denser granules significantly reduce airborne dust, creating a cleaner and safer working environment.
- Instant Dispersibility: Despite being in bead form, these granules are designed to break down and disperse instantly when added to water or resins.
- High Bulk Density: Allows for more efficient storage and transport compared to “fluffy” air-floated powders.

Versatility Across Industries
| Industry | Application | Key Benefit |
|---|---|---|
| Ceramics & Sanitaryware | Spray-Dried Body Mix | Ideal for dry-pressing tiles and high-tension porcelain; ensures uniform density in the mold. |
| Paints & Coatings | Masterbatches | Reduces “pigment dusting” in the plant and speeds up wetting time in high-speed mixers. |
| Catalyst Support | Chemical Processing | Provides a high-surface-area, uniform substrate for chemical catalysts. |
| Paper & Ink | Coating & filling | Controlled Tack & Rheology, Ink Hold-out, staple in the production of coated fine papers and lightweight coated (LWC) papers |
Pro Tip: If your production line uses automated weighing systems, switching from standard powder to Spray Dried Kaolin can improve dosing accuracy by up to 15%. The constant flow rate eliminates “bridging” in the hopper, which is the #1 cause of batch inconsistencies.
Applications
Why Choose Our Spray Dried Kaolin?
- Uniform Particle Size: Our precision atomizers ensure every bead is within a narrow size range, preventing segregation during shipping.
- Rapid Wetting Technology: Our granules are engineered with “micro-porosity,” allowing liquids to wick into the bead and dissolve it instantly without forming “fisheyes” (lumps).
- Enhanced Safety: By minimizing respirable dust, our spray-dried grade helps your facility meet strict air quality and occupational health (OSHA) standards.
- Optimized Moisture Balance: We control the drying temperature to ensure the beads retain just enough moisture to prevent static electricity while remaining bonedry for your process.
Efficiency at a Glance
- Reduced Waste: No more product left behind in the “corners” of bags or silos.
- Faster Loading: High bulk density means fewer bags to handle and faster silo filling.
- Cleaner Plant: Dramatically reduces the need for expensive dust extraction maintenance.
