- System accuracy (dynamic): ≤± 1~3%
- Modular Design: Easily adaptable to different belt widths.
- Sealing Effect: Prevents material leakage and air channeling.
- Wide Application: Suitable for various industries like mining and construction.
- Anti-Blockage: Spiral structure prevents material blockage.
- Viscosity Handling: Shaftless spiral design suitable for viscous materials.
Bincen Screw Feeder is a highly efficient device designed specifically for powder metering, widely used in industries such as mining and construction. It consists of a steady flow screw (or reamer) and a metering screw, featuring advanced unequal-pitch spiral shaft technology. Its blades, made of high-wear-resistant and corrosion-resistant materials, ensure stable material feeding with high strength and durability.
The steady flow screw has a variable pitch design to prevent material flushing and accommodate large flow requirements (for outputs >60 tons/hour, a double-tube steady flow is used). The large feed opening helps prevent arching in the silo, ensuring smooth material flow.
The thickened blade design enhances strength and extends its service life. Its anti-blockage structure effectively handles viscous materials, achieving high accuracy with a static precision of ≤±0.5% and dynamic precision of ≤±1~3%.
Application of Screw Feeder
Screw feeder is widely used in petroleum, chemical, textile, pharmaceutical, food, paper, beverage, environmental protection and other industrial production.

Function of Screw Feeder by Classification
1. Double Tube Spiral Metering Scale with Feeding Constant Flow Spiral
The upper spiral is used to isolate the pressure of the material in the silo on the scale. At the same time, the material conveyed is stable and uniform. The lower spiral realizes metering, which makes metering more accurate, stable, and reliable.
Basic product parameter information：
| Pipe diameter of spiral scale | Flow range |
| 160 | 1~5 |
| 200 | 5~10 |
| 250 | 10~20 |
| 300 | 20~30 |
| 400 | 30~60 |
| 500 | 60~120 |
2. Single Tube Spiral Scale
When there are other flow stabilizing devices above the metering spiral feed port, such as impeller feeder, screw machine, etc., the “single tube screw scale” can be used for metering (screw metering scale, screw quantitative feeder).
Single pipe and single layer simultaneously complete metering and conveying:
- Purpose: It can be used for conveying, called a “screw burning conveyor”; Available metering is called “spiral metering scale”.
- “≤ 1CM” spacing, perfect material locking, material gushing, material scattering, and material channeling are no longer possible.
3. Integral Metering Spiral Electronic Scale
The upper spiral is used to isolate the pressure of the material in the silo on the spiral scale, and the material conveying is stable and uniform. The lower spiral realizes metering; The lower spiral adopts three weighing sensors to lift the metering spiral completely and float it in the air, so that the weighing zero point changes little, the metering is more stable and reliable, and the repeatability is good.
