Longer lifetime required in cement mill
High deltaP resulted in short lifetime (actual: 24 mBar. Requested: 14 mBar)

- 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
