The kaolin production process involves mining, crushing, grinding, classification, and drying. Key equipment includes jaw crushers, hammer crushers, Raymond mills, and rotary dryers. The flowchart typically follows: Raw ore → Primary crushing → Secondary crushing → Grinding → Classification → Dewatering → Drying → Packaging.
Core equipment specifications:
| Equipment | Model | Capacity (t/h) | Power (kW) |
|---|---|---|---|
| Jaw Crusher | PE-400×600 | 15-40 | 30 |
| Hammer Crusher | PCΦ800×600 | 20-35 | 55 |
| Raymond Mill | 4R3216 | 3-8 | 37 |
| Rotary Dryer | Φ1.5×15m | 2-5 | >18.5 |
