In modern paint production, crushing and grinding are essential steps. Pigments and fillers in their raw form are coarse and uneven. Without grinding, paints suffer from poor gloss, low hiding power, uneven color, and storage instability.
The core equipment is the sand mill, where high-speed stirring drives grinding media to create shear, impact, and friction. This breaks pigment agglomerates into fine, uniform particles, reaching micron or even nano levels.
Grinding improves paint performance by:
- Enhancing gloss and silky feel
- Increasing hiding power
- Making colors purer and brighter
- Improving storage stability
- Extending durability and protection
Simply put, grinding is the cornerstone of high-quality paint, ensuring both beauty and long-lasting protection.
