Say goodbye to reunion and blockage! How does Navector airflow screen reshape fine powder screening accuracy?

Sieving low-density, easily agglomerated fine particles has always been a technical challenge in quality control processes in the pharmaceutical, chemical, and food industries. Traditional mechanical screening equipment often suffers from low screening efficiency and even mesh clogging when processing 10-micron powders due to electrostatic adsorption and sticky agglomeration between particles, compromising detection accuracy. To address this industry pain point, Navector's small negative pressure airflow sieve, with its innovative aerodynamic design, completely solves the global challenge of ultrafine powder screening.

1. Core Technology: Breakthrough Application of Airflow Dynamics

As a specialized device designed specifically for analytical sieves with pore sizes of 10 microns and larger, its operating principle revolutionizes traditional screening logic:

• Negative Pressure Environment Creation: By connecting to a vacuum cleaner or cyclone separator, a stable negative pressure field is created within the sieve chamber. The pressure differential at the nozzle generates a high-speed jet of air, creating a dynamic screening environment.
• Negative Pressure Suspension Screening: Particles smaller than the sieve aperture are carried through the sieve by the negative pressure, while particles larger than the sieve aperture remain suspended by the airflow, preventing sedimentation and accumulation.
• Self-cleaning effect: Airflow through the sieve apertures generates a reverse flushing force, automatically removing particles that could clog the sieve apertures, achieving simultaneous "screening and cleaning."

This design eliminates the need for mechanical vibration or ultrasonic assistance during the screening process, preventing the damage to the sample structure associated with traditional methods. For example, in the pharmaceutical industry, screening of cephalosporin APIs ensures particle morphology is intact, meeting the stringent GMP requirements for drug particle size distribution.

II. Precision Control: Intelligent Screening with Digital Parameters

The revolutionary nature of Navector's small negative pressure airflow screen lies not only in its innovative principle, but also in its fully digitally controlled parameters:

Multi-dimensional adjustable parameters:

• Negative pressure control: Adapts to materials of varying densities (e.g., plastic granules require high negative pressure, while food powders require low negative pressure);
• Nozzle speed: Optimizes dispersion by varying the airflow impact frequency;
• Screening time: Adjustable time allows for 3-5 times the efficiency of traditional vibrating screens.

Navector's small negative pressure airflow sieving system is ushering in an era of "precision control" for ultrafine powder screening. Its unique airflow screening technology not only solves the problem of agglomeration of low-density particles, but also, through fully digitalized and modular design, provides comprehensive solutions from R&D to mass production for the pharmaceutical, chemical, and food industries.
