Weigh Screw Conveyors & Feeders

Active Weighing Solutions Pivoted Weigh Screw Conveyors and Feeders are suitable for dusty and hazardous products and require only limited space.

The Pivoted Weigh Screw Conveyors and Feeders meets the need where a fully enclosed, dust tight system is required and existing infrastructure limits the suitability of other weighing solutions. Very similar in function to a fully enclosed Weigh Belt Conveyor or Weigh Belt Feeder, the Pivoted Weigh Screw provides an additional and cost effective dynamic weighing solution where existing space is limited.


Batching systems E.g. loading containers from a hopper using a pivoted weigh screw system to deliver a desired batched amount. Flowrate Control systems E.g. controlling product discharge from a feed hopper using the pivoted weigh screw to feed product into the process stream Pivoted Weigh Screw Conveyors and Feeders can be customized to suit many applications. In an application where continuous weighing or batching mode is required, the Pivoted Weigh Screw is fitted with an EMC MW95 controller. Where increased functionality and flow rate control is required, an EMC MW96A controller is fitted. The EMC ModWeigh display is highly customisable, readily allowing the display to be configured to suit the application.


  • Totally enclosed construction
  • Compact design
  • Monitoring or Flow Rate control
  • Flowrate output (4-20mA or 0-10Vdc)
