A new tool for removing impurities from powder materials – vertical airflow screen.

In industries where powder processing is critical—such as pharmaceuticals, chemicals, food production, and metallurgy—efficient, clean, and precise screening technologies are vital. The vertical airflow sieve has emerged as a highly effective solution for classifying powdery materials. By discarding traditional gravitational methods and adopting an innovative airflow-driven approach, this equipment offers a superior performance that enhances both quality and operational efficiency.

Vertical airflow sieve

Working Principle: Dynamic Airflow, Not Gravity

Unlike conventional screening equipment that relies primarily on gravity as the driving force for material separation, the vertical airflow sieve introduces a new operational concept—air as the carrier and kinetic energy as the driving force. In this system, the powder mixture enters the machine through a dedicated air inlet. Once inside, an intelligent turbo-boosting mechanism accelerates the material, dispersing agglomerates into finer particles and directing them uniformly toward the precision mesh screen.

This dispersed material is guided in the direction of the airflow, ensuring that fine particles pass through the composite screen in an orderly fashion. The design ensures that acceptable particles continue downstream into the next phase of production. Conversely, impurities and oversized contaminants are efficiently intercepted and discharged through an automatic slag outlet, completing a clean, selective separation process within a confined, dust-free environment.

Key Features and Advantages

  1. Vertically Installed Screen for Extended Lifespan
    One of the most notable design advantages is the vertical installation of the sieve mesh. This configuration ensures that the mesh bears no direct material weight, significantly reducing mechanical stress. As a result, the screen experiences minimal wear and tear, leading to a much longer operational lifespan compared to traditional vibrating or rotary sieves.
  2. Dust-Free Operation in a Negative Pressure System
    The entire screening system operates in a semi-closed negative pressure environment, which drastically reduces the risk of dust leakage. This not only improves workplace hygiene but also protects workers’ health and reduces environmental contamination—making the vertical airflow sieve particularly suitable for industries with stringent cleanliness standards.
  3. High Screening Efficiency
    By utilizing kinetic airflow energy rather than relying solely on gravity, the equipment achieves faster and more efficient particle separation. The intelligent turbo dispersion helps to prevent screen blockage, allowing the machine to maintain consistent throughput without frequent interruptions for cleaning or maintenance.
  4. Automatic Impurity Discharge
    The system is equipped with an automatic slag discharge port, enabling continuous operation even when dealing with materials that include a high percentage of impurities. This contributes to greater automation and reduces manual handling, boosting productivity and reducing labor costs.
  5. Compact and Space-Saving Design
    Despite its advanced capabilities, the vertical airflow sieve has a compact footprint, making it easy to integrate into existing production lines without requiring major layout changes.
