Case Study:

Nordic's pleated bags increased output & reduced emission level from 22 mg/Nm3/h to 1 mg/Nm3/h

Location: 

  • PORTUGAL

Operation:

Cement Mill

Dust type:

Cement dust

Problem:

  • Due to undersized dust collector, the cement mill produced only 27 t/h - the customer requested 30 t/h.
  • In addition, the customer experienced high emission levels and poor filter quality.

Solution:

By replacing 240 competitor pleated bags with 240 Top Loader Pleated Bags from Nordic Air Filtration, significant performance improvements were obtained:

  • The output of the cement mill increased from 27 t/h to 30 t/h
  • Emission level was lowered from 22 mg/Nm3/h to 1 mg/Nm3/h *
  • Improved Air-To-Cloth ratio eliminated pressure drop issues
  • More efficient cleaning; down to only 3 bar
  • Longer life cycle

* Individual results may vary based on application
