Ultrafine powder grinding (D97 ≤ 45μm) has become a critical process in industries ranging from pharmaceuticals to advanced materials. This technology enables superior material properties including enhanced reactivity, improved dispersion, and tailored particle size distributions.
| Technology | Fineness Range | Energy Efficiency | Typical Applications |
|---|---|---|---|
| Jet Milling | 1-50μm | Medium | Heat-sensitive materials |
| Ball Milling | 10-100μm | Low | Mineral processing |
| Roller Milling | 5-45μm | High | Industrial minerals |
Modern ultrafine grinding systems integrate precision air classifiers with:
| Parameter | Benchmark | Measurement Method |
|---|---|---|
| Specific Energy | <50 kWh/t (D97=10μm) | ISO 14887:2000 |
| Wear Rate | <5g/ton processed | ASTM G65 |
| Noise Level | <85 dB(A) | ISO 3744 |
For demanding ultrafine grinding applications (5-45μm), we recommend our SCM Ultrafine Mill series featuring:
The MTW Series Trapezium Mill offers superior performance for coarser applications (45-325μm) with:
| Component | Inspection Interval | Replacement Criteria |
|---|---|---|
| Grinding Rollers | 500 operating hours | Wear ≥ 15mm |
| Classifier Blades | 250 hours | Edge deformation ≥ 2mm |
Emerging technologies include:
Our SCM1680 Ultrafine Mill (315kW, 25TPH capacity) and MTW215G Trapezium Mill (280kW, 45TPH capacity) already incorporate IoT-ready interfaces for these advanced applications.
