Bag filter is a device used as a filter for dust or dirt particles from the air. In this device, the flow of air and dirty gas particles get into several filter vents (also called bags or cloth bags) which are parallel lined up, and leave dust on the filter. The use of this bag filter certainly has a very high filtering efficiency, even for very small particulates, it can be operated in dust conditions and in different flow volumes, there is energy conservation, there is no risk of causing water and soil pollution.
This tool is commonly used in the carbon black and cement industry as well as other industries that handle powders which, if left unchecked, will cause environmental pollution. The most important environmental pollution is air pollution in the form of particles (dust). Considering that the dust produced from the cement factory is actually a product (only imperfect), the dust caught by the particulate control equipment will be returned to the process until a product with the appropriate fineness is obtained.
