Single Shaft Screw Feeders
Single-shaft screw feeders are industrial equipment used for the quantitative conveying and stable feeding of powders, granules and small lumps. They are widely used in plastics processing, chemical, food, building materials and environmental protection powder systems.
This Inclined Screw Feeder Conveyor equipment uses a single spiral shaft to rotate within a closed or semi-closed tube, enabling continuous, uniform, and controllable material conveying. It is suitable for production processes that require high feeding accuracy and stability.
Working principle
The Single Shaft Screw Feeder uses a motor to drive the screw shaft to rotate, causing the material to move axially under the push of the screw blades.
During the transportation process:
- The material is continuously pushed by the spiral blades
- The conveying capacity is controlled by the rotation speed or frequency conversion system.
- It can achieve continuous or intermittent quantitative feeding.
- The sealed structure effectively reduces dust leakage.
Applicable materials
This equipment is suitable for a variety of industrial materials:
- PVC/PE/PP plastic powder
- Fillers such as calcium carbonate and talc
- Chemical Powders and Additives
- Food-grade powders and additives
- Cement, mineral powder and building materials
- Recycled powders and recycled materials
