Mini Negative-Pressure Airflow Sieve

【Material Requirements】：Specifically designed for the screening and analysis of low-density, easily agglomerated fine particles

【Product Overview】：Utilizing aerodynamic screening, this mini negative-pressure airflow sieve prevents agglomeration and ensures good sample dispersion. It is specifically designed for the screening and analysis of low-density, easily agglomerated fine particles. Compatible with analytical sieves of 10 μm and above, the screening process is gentle and requires no non-mechanical auxiliary components. The average screening time is 2–3 minutes. It can be used with a manually adjustable industrial exhaust system or optionally with an automatic exhaust system, providing continuous airflow to ensure repeatable screening results.

Product Introduction

Principle Introduction

The vacuum system is connected to the sieve, creating a negative-pressure environment inside the sieve chamber. Due to the pressure difference, a strong airflow is generated at the nozzle, which is directed onto the screen surface and then drawn through the mesh openings. Particles smaller than the mesh size pass with the airflow through the openings and are collected by the vacuum or a cyclone separator. The airflow helps to disperse the particles and also cleans the screen.

Equipment Advantages

• Uses air-jet technology to reduce agglomeration of fine particles

• Adjustable nozzle speed for more flexible screening
• Manual operation (standard) or automatic pressure adjustment (optional)
• All parameters fully adjustable (time, negative pressure, jet speed)
• Integrated silencer for quieter operation
• Connects to a vacuum system to create a negative-pressure environment
• Complies with all relevant ISO9001 standards for measuring equipment
• Ergonomic design for easy operation and maintenance-free use

Applications

Suitable for pharmaceuticals, chemicals, plastics, rubber, minerals, coated powders, pigments, colorants, ceramics, and food products.
