Equipment composition
A typical system is mainly composed of a steady flow feeding screw, a metering and conveying screw, a frequency converter, a load cell, a speed sensor and an electronic control system.
Performance characteristics
1. The feeding screw has a unique steady flow structure, and the feeding powder sinks evenly on the entire section of the feeding port, which is not easy to form arches and is not easy to punch the material.
2. The constant-flow feeding screw and the metering screw are synchronously adjusted in speed. The filling factor of the constant-flow feeding screw is 1.0, and the filling factor of the metering screw is 0.6. High precision
3. The helical blade is made of manganese steel material, which has strong wear resistance and long service life.
4. The spiral gap is small, which overcomes the problem of backflow punching and avoids the adhesion of materials in the gap of the pipe wall.
5. Sealed structure to reduce dust spreading
