AI Technical Summary

Technical Problem

Existing airflow mixers suffer from high energy consumption, long mixing time, insufficient mixing uniformity, and serious dust pollution when mixing powder materials, especially for materials with different densities and properties.

Method used

The device employs an airflow mixing unit with positive and negative pressure conveying. The negative pressure component smoothly draws in materials, while the pressurization component generates a powerful positive pressure airflow. Combined with the airflow mixing component and the dust removal component, it achieves efficient, uniform mixing and clean conveying of materials.

Benefits of technology

It improves mixing uniformity, reduces material loss and environmental pollution, shortens mixing time, improves production efficiency, and ensures accurate material delivery in complex pipeline layouts.
