Automatic Screw Feeder
An automatic screw feeder is an industrial device used for the automatic quantitative conveying of powder and granular materials. It is widely used in plastic compounding, chemical feeding, food processing, and industrial automation production lines.
This equipment combines a screw conveyor structure with an automatic control system to achieve continuous, stable, and high-precision material feeding, effectively improving the level of production automation and reducing human error.
Working principle
The Automatic Screw Feeder uses a motor to drive a rotating screw shaft, which evenly transports materials from a hopper or storage bin to the target equipment.
In automatic control mode:
- PLC or frequency converter system to adjust screw speed
- Achieve precise material feeding according to the set flow rate
- Cement Screw Conveyors and Feeders can be linked with the weighing system to achieve closed-loop control.
- Continuous or intermittent automatic feeding modes are available.
Applicable materials
This equipment is suitable for a variety of powder and granular materials:
- PVC/PE/PP plastic powder
- Fillers such as calcium carbonate and talc
- Chemical powders and additives
- Food-grade powders and ingredients
- Cement, mineral powder and building materials
- Recycled plastic powder and mixture
