Product Description
In modern plastic extrusion and automatic batching systems, accurate material feeding is essential for maintaining product quality, production efficiency, and stable machine operation. The Single Screw Loss-in-Weight Feeder developed by Zhangjiagang Chenxing Machinery Co., Ltd. is designed to provide continuous, precise, and intelligent gravimetric feeding for various plastic processing applications.
This feeding system is widely used in plastic extrusion lines, recycling systems, compounding production, and automatic dosing applications where stable feeding performance is required.
A single screw loss-in-weight feeder is a gravimetric dosing system that continuously measures material weight reduction over time and automatically adjusts screw speed to maintain accurate feeding rates.
Compared with traditional volumetric feeders, this system offers significantly higher precision and stability.
The equipment mainly consists of:
Feeding hopper
Single screw conveying system
Precision load cells
PLC intelligent control system
Servo motor drive
Automatic feedback regulation
The system continuously calculates material discharge based on weight loss, ensuring stable and reliable material feeding throughout the production process.
The gravimetric weighing system ensures stable and precise material feeding, helping manufacturers improve product consistency and reduce raw material waste.
The single screw structure is ideal for:
Plastic granules
Masterbatch
Virgin resin
Regrind materials
Powder materials with good flowability
The equipment provides smooth and continuous material output, helping maintain stable extrusion pressure and production quality.
The system adopts advanced PLC automatic control with real-time monitoring and automatic speed adjustment for precise feeding performance.
The modular structure allows operators to easily disassemble, clean, and maintain the equipment, reducing downtime and maintenance costs.
Optimized screw design and intelligent motor control help lower energy consumption while improving production efficiency.
The equipment is widely used in:
PVC pipe extrusion
PE pipe extrusion
Profile extrusion
Sheet extrusion
Pelletizing lines
Reprocessing systems
Plastic granule feeding
Masterbatch production
Additive dosing
Filler mixing
Automatic batching systems
Powder conveying systems
Continuous dosing applications
