System, developed for the cement industry, uses one Bag Filter to dedust both the kiln & raw mill and the clinker cooler. For the Metals & Mining and Oil & Gas industries, we created Multi-Input Integrated Systems, which collect flows from several process points or units and converge them into one Bag Filter (ex:
Baghouse Basics. We briefly describe the process in selecting the right solution for your process conditions. The process gas temperature and the type of particulate are key to determining the media material used in the fabric filter. The media material, or filter media is the cloth or cloth-like material that forms the bag.
