A High Frequency Vibrating Screen is an advanced screening device used in various industries to separate materials by size with exceptional efficiency.
Screening machines with high frequency drive operates at a much higher frequency—typically 2900 to 6000RPM—allowing finer materials to pass through the fine sand screen mesh while larger particles are retained. This high frequency screen reduces the surface tension of the material bed, enabling better stratification and improved screening accuracy.
1.The High Frequency Vibrating Screen adopts either a high-frequency hydraulic vibration control system or a multi-motor vibration control system, delivering high-frequency vibrations (2900–6000 RPM) directly to the screen mesh. This effectively prevents screen clogging during powder screening, fine material classification, and manufactured sand processing, thereby maximizing throughput.
Compared with conventional screening equipment, high frequency screen offer higher screening efficiency and greater capacity, with improved adaptability to wet and sticky materials. The High Frequency Vibrating Screen Mesh is generally installed at an inclination of 38–43 degrees, but an adjustable tail-end vibration motor can be added to reduce the angle (to 20–25 degrees) and overall installation height. Auxiliary airflow can also be integrated to further enhance fine sand screen performance.
2、Small amplitude: Fine particles are more likely to contact the fine sand screen surface, increasing the probability of separation and significantly improving screening efficiency.
3、High frequency: The direct vibration on the high frequency vibrating screen mesh enables rapid stratification of material, resulting in superior anti-clogging performance. With auxiliary airflow, a minimum cut size of 300 μm can be achieved.
4、Quick tensioning system: The external rapid tensioning mechanism allows for quick fine sand screen changes, significantly increasing equipment uptime and reducing maintenance costs.
5、Non-vibrating screen frame: The fine sand screen frame itself remains static during operation, reducing civil engineering and installation costs, improving sealing, and enhancing environmental protection.
6、Lower energy consumption: Compared to conventional equipment with the same processing capacity, the high frequency screen consumes less energy, lowering operational costs.
7、Low noise operation: Provides a more environmentally friendly and user-friendly working environment.
8、Capacity: For finished materials below 2 mm, throughput of high frequency screen ranges from 10 to 50 tons per hour.

Range of Configuration
1.The high frequency screen is widely used across various industries due to its superior precision and efficiency. Its primary application is in the classification of fine materials, particularly in manufactured sand, mineral processing, and powder screening.
2.The fine sand screenare especially effective in separating particles smaller than 2 mm, making high frequency screen ideal as a fine sand screen for grading and quality control in sand production lines. Screening machines with high frequency drive deliver rapid vibrations directly to the high frequency vibrating screen mesh, significantly enhancing stratification and preventing clogging, even with wet or sticky materials.
3.In mining and mineral processing, high frequency screen are used to separate valuable minerals from gangue with high precision. The high frequency vibrating screen mesh allows for efficient separation down to 300 μm when combined with auxiliary airflow, making fine sand screen suitable for powder classification and dry screening of ultrafine materials.
4.Additionally, these screening machines with high frequency drive are applied in industrial sectors such as food processing, chemicals, and recycling, where fine particle separation is crucial. Thanks to their low energy consumption, high capacity, and quick screen change capabilities, fine sand screen have become essential equipment in modern fine material processing systems.
