Across the powder handling industries screw feeders are used to control the flow of material from a dispenser or hopper into a process. The properties of the powder have a direct impact on the performance of the feeder making it essential to tailor the design and operating conditions of any given system to the specific powder being handled. A poorly matched powder/feeder combination will typically be associated with low feed rates, high screw torques and the accumulation of powder on the auger walls. All these factors decrease both short and long term operating efficiency.
