After an extensive series of tests on a pilot plant at Scheuch’s in-house Technikum (Tech Center), the use of 8-meter long filter bags in large-scale cement plants was first approved in 2005 despite initial reservations within the cement industry.

Since then, this length of filter bag has become the industry standard. Positive findings based on actual measurements confirmed the thorough cleaning of the EMC filter across the overall length with the same low differential pressure level as with shorter filter bags.

8-m filter bags - standard by Scheuch

Last year, Scheuch was also able in the course of additional and intensive R&D efforts to transfer the previous advantages of EMC technology to applications using 10-m filter bags and verify these advantages in actual practice. Based on convincing long-term testing using representative dust types and filter media for cement grinding plants and kiln dedusting systems, as well as comparative measurements using different bag lengths, it was possible to confirm a virtually identical filtration behavior as the basis for sufficient operating reliability.

10-m filter bags in practice

Holcim (Deutschland) AG was the first customer to order from Scheuch an EMC filtration plant equipped with 10-m filter bags for the planned conversion of the kiln dedusting system at its plant in Lägerdorf.
Meanwhile the system is into operation, to the fullest satisfaction of our customers,  and confirms the great advantages of the larger filter bags.
