Farrleey® Dust Pleated Bag Cartridge Applied In Cement Industry
One of our customers in cement industry, which clinker production line capacity is 5000 T/D, but the assorted cement grinding mill filter bag dust collector emission was 20mg/m3, in order to drop to no more than 10mg/m3 to meet Chinese environmental latest ultra-low emission regulation, the bid for this transformation project was won by Farrleey. Base on the on-site investigation and evaluation of the dust collector’s operation condition, dust characteristic, dust cleaning mechanism and production and energy consumption , finally the overall optimization and transformation scheme for bag filter was finalized. The core filter element was chosen Uoxxon® pleated bag cartridge, filter media is needle felt, which is a very specialized media to suit cement application.
The case was completed in March, 2020 and put into operation at the same time. Till now, the continuous emission of the bag filter in the cement mill section has reached the standard. The comparison of operating parameters as follows:
| Project | Unit | Before | After | Remarks |
| Operating Resistance | （Pa) | 2400-2800 | 800-1000 | Although Reduce operating load, it can still maintain the original production capacity. |
| Operating Load | （%) | 90% | 50% | |
| Electricity | （A） | 36 | 27.7 | |
| Capacity | （t/h） | 85 | 85 | |
| Emission | （mg/m3) | 20 | 5-7 |
