A bag filter assembly was newly constructed and tested for its operating characteristics and dust-collection efficiency by using the limestone dust particles. The test results observed in the assembly are summarized as follows
1. The collection yields of the newly estabished bag filter have continuously increased with theelapsing time of operatinn, and reached to about 99% after 20 hours of operatinn, during which the pressure drops at the respective test sections of the dust generator, the bag filter, and the check filter have shown constant values about 3∼4mm H₂O.
2. The particle size distribution of the limestone powder used in the experiments ranges from 2 to 55 ㎛, which were measured by the image analyser. The average particle size of the dust collected in the bag filter was about 13∼18㎛ and those collected in the check filter were about 4.5∼4.8㎛
