Failure analysis of bag dust collector

Bag dust filter is widely used as it has many advantages, but once the bag failure, it will cause dust emissions exceed the standard and huge bag replacement cost. Failure problems of bag dedustor appear often in cement industry were summarized in detail, including mechanical abrasion, air wear and temperature failm＇e. Aiming at these problems, avoid and preventive measures were pro- posed. As long as the material is reasonable, manufacture and installation quality is guaranteed, and plus proper maintenance and oper- ation, bag dust collector can completely meet the more and more strict requirements of national dust emission standards.
