High-Speed Screening Machine

The Navector High-Speed Intelligent Screening Machine is a newly upgraded high-performance fine screening system developed based on the original ultrasonic small particle screening machine. It is specifically designed for the screening of ultrafine powders with a D50 particle size and particles below 1 μm.The machine adopts low-frequency, high-speed vibration technology with a speed range of 0–3000 rpm and stepless speed regulation, allowing screening parameters to be flexibly adjusted according to different material characteristics. At the same time, it retains the classic flower-disc adjustment structure, achieving simultaneous improvements in screening accuracy and processing capacity.

To meet the growing demand for ultrafine powder screening driven by the rapid development of the new energy industry, including solid-state batteries, lithium iron phosphate batteries, and ternary batteries, the Navector High-Speed Screening Machine effectively addresses common issues encountered by traditional screening equipment, such as mesh blinding, poor classification efficiency, and insufficient throughput. It provides a more stable and efficient screening solution for the production of advanced energy materials.

Equipment Advantages

High Screening Accuracy

Specifically optimized for ultrafine powders with a D50 particle size and particles below 1 μm, the machine effectively improves incomplete screening and poor classification issues commonly found in conventional screening equipment, enhancing particle size consistency.

Significantly Increased Throughput

Utilizing low-frequency, high-speed vibration technology, the machine greatly increases processing capacity while maintaining high screening accuracy. Throughput can reach up to five times that of conventional screening machines and three times that of traditional small particle screening machines.

Extended Screen Mesh Service Life

Equipped with the Magnetet specialized screen mesh as standard, featuring high tension, excellent wear resistance, and high screening efficiency. The mesh tension can reach 50 N, with a service life 2–3 times longer than ordinary screen meshes.

More Flexible Parameter Adjustment

The 0–3000 rpm stepless speed control system allows operating speed to be flexibly adjusted according to different material properties.

Low Upgrade Cost

Existing small particle screening machines can be upgraded without replacing the entire machine. Only the variable-speed motor and control system need to be upgraded, resulting in lower investment and faster returns.

Ideal for New Energy Ultrafine Powders

Developed specifically for ultrafine materials such as sulfide solid electrolytes, high-nickel single-crystal materials, and single-crystal lithium iron phosphate fine particles. It effectively reduces mesh blinding, improves classification performance, and increases throughput for long-term stable operation.

Working Principle

The Navector High-Speed Screening Machine utilizes low-frequency, high-speed vibration technology combined with a 0–3000 rpm stepless speed control system, enabling materials to disperse rapidly across the screen surface and pass through the mesh efficiently. For ultrafine powders that are prone to agglomeration and mesh blinding, the machine improves screening efficiency and classification accuracy by optimizing material movement trajectories and screening conditions.

Combined with the high-performance Magnetet screen mesh, the system minimizes mesh blinding and particle lodging while extending screen service life. While maintaining high screening accuracy, it delivers greater processing capacity and continuous stable operation, making it particularly suitable for precision screening and classification of ultrafine powders in lithium battery, solid-state battery, and related industries.

Applications

Widely used in industries such as solid-state batteries, lithium batteries, advanced materials, electronic materials, and fine chemicals. It is suitable for the precision screening and classification of sulfide solid electrolytes, high-nickel single-crystal materials, single-crystal lithium iron phosphate fine particles, conductive additives, and other ultrafine powder materials, meeting the requirements for both high-precision and high-capacity production.
