Baghouse in Cement Plants: Understanding How They Work and Maintenance

Baghouses are designed based on the size of the cement baghouse building and the volume of the dust emissions. Large plants tend to have more numerous and larger baghouses than small plants. For example, a cement plant that has a production capacity of 1 million metric tons per year will have around six to eight baghouses.
