[Howin Machinery Tips] Screen Clogging in Airflow Sieves? Solutions for High-Humidity and High-Viscosity Materials!

During the use of airflow sieves, many users experience screen clogging—especially when handling high-humidity or high-viscosity materials. This not only affects screening efficiency but also increases equipment maintenance costs. As a professional manufacturer of vibrating screening equipment, Howin Machinery is here to analyze the root causes of this issue and offer effective solutions!

1. Why Do High-Humidity/High-Viscosity Materials Tend to Clog the Screen?
Material agglomeration: Moisture or viscous components cause particles to stick together and adhere to the screen, blocking sieve openings.

Electrostatic adsorption: Fine, dry powders easily generate static electricity and stick to the screen surface, forming clumps.

Smeared screen openings: Excess moisture can turn the material into a paste, sealing the mesh apertures.

Poor air dispersion: Sticky materials tend to clump, preventing the airflow from penetrating and reducing screening efficiency.

2. How to Solve Screen Clogging for High-Humidity/High-Viscosity Materials?
1. Pre-treat the Material
✅ Reduce moisture content: Use drying or air-drying methods to lower material humidity.
✅ Add flow aids: Use talcum powder, silica, etc., to reduce stickiness and improve flowability.

2. Optimize the Screening Equipment
✅ Use anti-blocking mesh: Choose ultrasonic or self-cleaning screens to reduce material adhesion.
✅ Adjust airflow pressure: Properly increase the air pressure to enhance material dispersion.
✅ Install mesh cleaning devices: Add bouncing balls, brushes, or air-jet systems for real-time screen cleaning.

3. Improve Operational Methods
✅ Control feeding speed: Avoid overfeeding at once to prevent material buildup and clogging.
✅ Intermittent screening: Pause briefly for cleaning to prevent long-term adhesion.
✅ Adjust screening angle: Optimize the angle of the airflow sieve to improve material flow.
