From Fine Screening to Precision Screening: Another Breakthrough in NHFF High-Frequency Screen Technology

The original intention behind the development of the NHFF series high-frequency screen was to solve the filtration challenges of BYD’s viscous battery material slurry. Due to its outstanding efficiency and unique performance, the equipment has also demonstrated excellent results in filtering slurries and pastes in other industrial production applications.

I. Working Principle

Through a specially designed high-efficiency vibration motor, the synchronous vibration frequency reaches 2000 times per minute. Equipped with a single-layer screen featuring a special tensioning design, the slurry can be rapidly separated.

II. Equipment Advantages

• High efficiency and high precision in slurry filtration, with particularly remarkable results for viscous slurry
• Capable of meeting higher mesh size requirements
• Simple disassembly design—only requires turning the handle to open the main unit, making cleaning and maintenance convenient
• Lightweight, compact body, easy to move, and better suited to production needs
• Synchronous vibration frequency reaches 2000 times per minute, enabling rapid slurry separation
• Special screen tensioning design allows for quicker screen replacement
• Equipped with a single-layer screen for higher efficiency

III. Application Fields

Applied in battery slurry, aluminum paste, ceramic glaze, chocolate slurry, liquid additives in food production lines, various laboratory slurries, clay materials, and high-grade coatings.
