Case Study:
Longer lifetime required in cement mill
Location:
- SWITZERLAND
Operation:
Cement mill
Problem:
High deltaP resulted in short lifetime (actual: 24 mBar. Requested: 14 mBar)
Solution:
Installation of Pleated Bag from Nordic Air Filtration

| BEFORE | AFTER | |
| Bag filter | Pleated bag solution | |
| Airflow in unit | 90.000 m³/hour | |
| Dusttype | Milled clinker dust | |
| Collector running hours/year | 7260 | |

Advantages:
- Less wear of the filter media due to larger dropout box (2,82m shorter filter) = "Gravity-filtration" separates the larger dust particles
- Lower dP.
- Lower emission than with conventional filter bags = emission below customer limit 20mg/m3.
- After 22 months running time customer is still satisfied with the solution and has since ordered for additional cement mill
