Predicting feeder performance from powder flow measurements
Predicting feeder performance from powder flow measurements

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.

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.
