| Résumé : |
Tests were carried out to demonstrate the different effects milling parameters have on power input, energy efficiency and production capacity. A new grinding technology allows power input and thus production capacity to be increased while reducint the specific energy requirement. |
| Note de contenu : |
- How operating parameters affect production efficiency
- Practical evaluation of theoretical predictions
- Maximising output with best energy efficiency
- Optimisation of an existing PEG grinding system
- Benefits of the revised machine set-up
- results of field tests with real customer products
- Constant quality with lower energy and higher output
- FIGURES : 1. Efficiency of comminution of limestone with differential speeds of the agitator shaft - 2. Comminution rsults as a function of the stress energy of the grinding beads - 3. Calculation of optimum grinding bead size to maximise milling efficiency - 4. Comminution of limestone with different circumberential agitator shaft speeds and variation of the grinding bead size - 5. Production capacity as a function of operating parameters - 6. Basic representation of the 'Neos' grinding system - 7. Performance increase achieved by switching from "Zeta 25" (LMZ 25) to "Neos 20" grinding system for various customer products
- Table : Effects of rotor speed v, on specific energy efficiency SE when milling limestone and of reducing bead size d (in fourth group of results) |
