Pollen Powder Screening: High-Efficiency, Low-Damage Solution with Ultrasonic Vibrating Screen

A customer from the natural plant extract and health supplement industry required a customized Pollen Powder Ultrasonic Vibrating Screen solution for continuous screening production. The project URL /pollen-powder-ultrasonic-vibrating-screen/ focuses on maintaining material structure while improving screening efficiency. Since pollen is an active material, preserving its biological properties and application value during screening was a critical requirement.

Pollen Powder Ultrasonic Vibrating Screen Customer Requirements

Following the client’s detailed clarification of the material’s characteristics, we placed particular emphasis on the stability requirements of the on-site production environment. Given that the pollen powder processed by the ultrasonic vibrating screen is lightweight and highly prone to floating, the open-screen sifting process is susceptible to airflow interference, which can lead to dust dispersion and increase the risk of material loss. Consequently, the client requested that the equipment—while maintaining high screening efficiency—also feature excellent sealing capabilities and effective dust control mechanisms to ensure both the cleanliness of the production workshop and a high material recovery rate.

• Material: Pollen powder and granular mixture with irregular particle shapes
• Particle distribution:
  • Approximately 30%: 3 mm
  • Approximately 20%: 0.73–3 mm
  • Approximately 50%: <0.73 mm
• Capacity requirement: 200kg/h
• Material structure must remain intact during screening
• Reduce mesh blockage and improve continuous operation stability
• Suitable for fine classification and impurity removal

The customer specifically noted:

Pollen is an active material. Traditional high-vibration screening methods often damage its structure and reduce the effectiveness of active ingredients, which was the main problem with previous equipment.

Pollen Powder Ultrasonic Vibrating Screen Solution

Based on the material characteristics:

• Lightweight materials tend to agglomerate and block conventional screens
• A high percentage of larger particles requires a strong throughput capability
• Ultrasonic technology was integrated into the vibrating screen system for improved screening performance

During the design phase, we implemented specific optimizations to address the electrostatic properties of pollen within the ultrasonic vibrating screen system. By enhancing the equipment’s grounding and refining the screen mesh structure, we effectively minimized the impact of electrostatic adsorption on the screening process. Concurrently, we implemented a matched control strategy for the feed rate to ensure uniform material distribution across the screen surface—thereby preventing localized accumulation—which further enhanced the overall screening stability and continuous operational capability.
