Products Description
Bellian Single Tube Feeder is a simple and practical feeding equipment used for quantitative feeding of powdery materials. It is widely used in cement plants, power plants, chemical plants and other industries. Our single tube feeder adopts spiral feeding principle, which has simple structure, reliable operation and low maintenance cost. It can adjust the feeding quantity steplessly, and is suitable for short distance transportation and quantitative feeding of powder materials.
Working Principle
The single tube feeder mainly consists of tube casing, spiral shaft, driving device and inlet/outlet. The spiral shaft is equipped with continuous spiral blades. When the machine works, the driving device drives the spiral shaft to rotate. The materials are pushed forward by the spiral blades along the tube. The feeding quantity can be adjusted by changing the rotation speed of the spiral shaft or adjusting the opening of the inlet gate.

Buying Guide
When choosing a single tube feeder, you should consider: 1. The type and properties of materials; 2. The required feeding capacity; 3. The transportation distance; 4. The material requirements (carbon steel or stainless steel). We will recommend the most suitable model according to your specific requirements.
FAQ
What is the difference between single tube feeder and screw conveyor?
Single tube feeder is more suitable for short distance quantitative feeding of powder materials, with simpler structure and lower cost. Screw conveyor is more suitable for longer distance transportation and has larger capacity. Single tube feeder is often used in batching systems where accurate feeding is required.
Can the single tube feeder transport wet materials?
The single tube feeder can transport wet materials with moisture content below 20%. However, it is not suitable for transporting highly viscous or easily caking materials, which may cause blockage.
How to adjust the feeding quantity?
The feeding quantity can be adjusted by changing the rotation speed of the spiral shaft using a frequency converter, or by adjusting the opening of the inlet gate. Frequency converter adjustment provides more accurate and stepless control.
What is the maximum transportation distance of the single tube feeder?
The maximum transportation distance of our single tube feeder is 20 meters. For longer distance transportation, we recommend using screw conveyor or chain conveyor.
