Cleanly separated – Filters in fluid bed systems, an overview (German article)

Today, fluid bed systems are used in a variety of ways for the production and refinement of bulk materials. For the production of granulates from solid and/or liquid raw materials and the coating of particles (coating), fluid bed plants offer many possibilities for influencing the granulate properties. The process chamber of fluid bed systems must be permeable to the process gas at the bottom and at the top. It is usually bounded at the bottom by an inflow floor and at the top by a filter. The filter is thus of decisive importance for the process.
