What Is a Twin Screw Loss-in-Weight Feeder?

A twin screw loss-in-weight feeder uses an intermeshing twin screw structure combined with real-time weighing technology to precisely control material feeding rates.


The equipment continuously monitors hopper weight changes and automatically adjusts screw speed through the PLC control system.


Compared with single screw feeders, the twin screw structure provides better:

  • Material conveying stability

  • Anti-bridging performance

  • Feeding uniformity

  • Powder handling capability

This makes it ideal for difficult-flowing materials.



Main Features of Twin Screw Loss-in-Weight Feeder

Excellent Feeding Accuracy

Real-time gravimetric weighing ensures highly accurate and stable feeding performance even under low feeding rates.


Ideal for Poor Flowability Materials

The twin screw structure is suitable for:

  • PVC powder

  • Calcium carbonate

  • Wood powder

  • Talc powder

  • Fine chemical additives

  • Lightweight flakes

  • Sticky materials


Anti-Bridging Design

The intermeshing twin screws effectively prevent:

  • Material bridging

  • Hopper blockage

  • Feeding interruption

  • Uneven discharge

ensuring stable continuous operation.

Self-Cleaning Function

The twin screw system features partial self-cleaning capability, reducing material residue and improving production cleanliness.

Intelligent Automatic Control

Advanced PLC control system provides:

  • Real-time feeding adjustment

  • Data monitoring

  • Alarm protection

  • Automatic calibration

  • Stable dosing performance


Stable Material Flow

The system improves feeding consistency and helps maintain stable extrusion pressure and product quality.
