In a recent study, Freeman Technology and Gericke carried out experiments to determine whether measured flow properties of a powder correlated with screw feeder performance and whether the values could then be used to predict feeder performance when conveying powders

Screw feeders are used in many industries to control the flow of powder into a process. The properties of the powder have a direct impact on feeder performance, making it essential to tailor the system to the product being handled. Poorly matched powder/feeder combinations can result in low feed rates, high screw torques and the accumulation of powder on the walls, all of which decrease short- and long-term operating efficiency.
