Case Study:
Milling of TiO2 - New dustcollector
Location:
- SLOVENIA
Operation:
TiO2 Milling
Dust type:
TiO2
Problem:
Former solution in reverse air dust collector with ring bags gave following problems:
- Lifetime only 1 year
- Emission above 20mg/m3. Below 10mg/m3 was required.
Solution:
New dust collector from OEM with Pleated Bag from Nordic Air Filtration installed March 2016.
