Kaolin clay, a vital industrial mineral, demands precise ultrafine grinding to unlock its full potential in ceramics, paper coating, and advanced material applications. Modern milling technology has revolutionized kaolin processing, enabling producers to achieve sub-5μm particle sizes with unprecedented energy efficiency. This article explores cutting-edge solutions for kaolin refinement, focusing on technological breakthroughs that redefine productivity benchmarks.
Kaolin’s plate-like crystal structure and variable hardness (Mohs 2-2.5) present unique processing challenges:
| Challenge | Impact | Solution |
|---|---|---|
| Soft particle agglomeration | Reduced grinding efficiency | Shear-force dominant milling |
| Moisture sensitivity | Clogging risk | Closed-circuit drying system |
| Platelet structure preservation | Product quality requirement | Controlled compression grinding |
Our SCM Ultrafine Mill series delivers exceptional performance for high-value kaolin applications requiring 5-45μm particle sizes:
| Model | Capacity (t/h) | Power (kW) | D97 Range |
|---|---|---|---|
| SCM800 | 0.5-4.5 | 75 | 325-2500 mesh |
