The Twin Screw Loss-in-Weight Feeder from Zhangjiagang Chenxing Machinery Co., Ltd. is specially designed for high-precision feeding of powders, lightweight materials, and difficult-flowing raw materials used in plastic extrusion, compounding, and recycling systems.
With advanced twin-screw conveying technology and intelligent gravimetric control, the system ensures continuous, stable, and highly accurate material dosing.
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.
Real-time gravimetric weighing ensures highly accurate and stable feeding performance even under low feeding rates.
The twin screw structure is suitable for:
PVC powder
Calcium carbonate
Wood powder
Talc powder
Fine chemical additives
Lightweight flakes
Sticky materials
The intermeshing twin screws effectively prevent:
Material bridging
Hopper blockage
Feeding interruption
Uneven discharge
ensuring stable continuous operation.
The twin screw system features partial self-cleaning capability, reducing material residue and improving production cleanliness.
Advanced PLC control system provides:
Real-time feeding adjustment
Data monitoring
Alarm protection
Automatic calibration
Stable dosing performance
The system improves feeding consistency and helps maintain stable extrusion pressure and product quality.
The equipment is widely used in:
PVC compounding
Filler masterbatch
Engineering plastics
Additive dosing
Pulverized material feeding
Powder dosing systems
Recycled material processing
Pipe extrusion
Profile extrusion
Sheet production
High-output extrusion lines
Fine powder conveying
Automatic batching
Continuous dosing systems
Modern plastic manufacturers increasingly prefer twin screw gravimetric feeders because they help:
Improve product consistency
Reduce material waste
Prevent feeding instability
Increase automation level
Improve powder handling performance
Optimize overall production efficiency
Especially in PVC powder applications, twin screw feeders offer significant operational advantages.
