Screw Feeders

Screw feeders are used in various industries for the metering of material into a production process. Screw feeder design closely resembles that of a screw conveyor, but unlike a screw conveyor, a screw feeder is required to be very precise and accurate. The screw in a screw feeder is completely filled with material, compared to a screw conveyor which is typically 40-50% filled. That is part of the reason the material is accurately discharged when the feeder screw is rotating at a controlled rate.

Application Challenges:

• Fast Response
  Capable of accurately regulating material feed.
• Load Detection
  Capable of detecting an overload or no material in the screw situation.
• Speed Range
  Be able to provide the required amount of torque throughout the speed range.
• Trip-less Operation
  The product must be capable of continuing to operate after a momentary power loss or a fault
