New cement plant filter media improve performance

Two new bag filters from Donaldson Membranes installed on Belgian cement plant used for dedusting kiln exhaust gases and cooler gases, to increase capacity

Donaldson Membranes were recently chosen as the supplier of filter media for bag filters as part of the overhaul of the dry process line at the CBR Heidelberg Cement Lixhe plant.

CBR Heidelberg Cement, a world-leading producer of cement, concrete and building materials, shut down the Lixhe wet process kiln and carried out a complete modernisation of the dry process production line in order to.

1 increase capacity from 3400 to 4200 tpd.

2 maximise the use of the most profitable secondary fuels.

3 meet environmental protection standards.

As part of this project, two bag filters were installed for dedusting kiln exhaust gases and cooler gases.

The filter bags were manufactured in Tetratex Woven Glass fabric with Tetratex Ultra High Efficiency ePTFE membrane, suitable for continuous service at temperatures of up to 260C.

Donaldson Membranes, worldwide manufacturers and suppliers of expanded PTFE membranes, films and laminates, recommended Tetratex with its requirements for lower pressure compressed air and less frequent cleaning due to its exceptional dust cake release properties, whilst giving: near zero particle emissions; increased bag life; and lower maintenance costs.

The choice of bag filter media technology at the Lixhe plant was based on the excellent performance of Donaldson Membranes products.

Tetratex ePTFE membranes are used in many parts of the cement process, giving improved airflow throughput, which translates into increased production rates.

Tetratex ePTFE membranes have become a significant market player as the fabric and technology of choice in the replacement of electrostatic precipitators (ESP) with baghouse filters in the kiln de-dusting process.
