Handling powders and bulk solids can be considerably more challenging than dealing with liquids and gases. These difficulties often arise due to a lack of adequate training, leading to a reliance on trial-and-error methods. Bulk solids and powders frequently encounter various flow challenges, including bridging, ratholing, flooding, and inadequate flow rates, and more.

Many of these flow issues can be traced back to improper discharger or feeder designs. Effective feeder design not only enhances the flow within bins, hoppers, and stockpiles but also positively influences product quality. Join our webinar to gain valuable insights into common feeder-related flow problems and receive essential design recommendations that can significantly benefit your operations.
