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.

Principle Introduction

The core classification principle of this equipment is based on the perfect combination of dynamic centrifugal sedimentation and laminar flow separation technologies, ensuring a precise, controllable, and gentle separation process without shear damage. It achieves high-precision, low-damage, and high-efficiency classification in a wet environment, meeting the stringent requirements of next-generation materials for monodispersity, purity, and morphological integrity.

Classification Process

• Establishment of the Centrifugal Force Field:
  The slurry enters the interior of a high-speed rotating drum. Under the action of strong centrifugal force, particles begin to settle according to their size and density differences. Larger/heavier particles experience greater centrifugal force.
• Laminar Separation and Precise Cut:
  Inside the drum, a specially designed laminar separation zone is present, where the liquid flow is highly stable (laminar).
  Particles of different sizes follow different trajectories under the balance of centrifugal force and fluid drag.

• Particles larger than the cut size: Overcome the fluid drag and settle on the drum wall, discharged or collected continuously as “coarse material.”
• Particles smaller than the cut size: Carried by fluid drag, remain suspended in the liquid, and overflow from the drum as “fine material.”

Equipment Advantages

• High Flexibility: Can operate as a standalone unit for batch processing or be easily integrated into continuous automated production lines.
• Closed-Loop Option: Coarse materials can be returned to the upstream mill for reprocessing, improving raw material utilization and achieving zero waste.
• Stable Process Scale-Up: From laboratory to pilot to large-scale production, the classification principle remains consistent, and process parameters can be precisely scaled.

Principle Introduction

The basic working principle of a disc stack centrifuge is to separate different components in a mixture based on density differences. This is achieved by rotating a bowl containing the mixture at high speed, generating centrifugal force that drives denser particles or liquids outward toward the bowl wall, while less dense fluids move inward toward the center.

The disc stack inside the bowl significantly increases the effective separation area, thereby enhancing separation efficiency. The conical discs in the stack form a series of narrow channels through which the fluid must pass. As the fluid flows through these channels, denser particles or liquids are forced toward the bowl wall, while lighter fluids migrate toward the center.

Principle Introduction

The main operating principle of this silver paste filtration machine is to automatically achieve material filtration through pressurized filtration combined with ultrasonic vibration technology. The equipment is designed with an agitator blade system; when impurities accumulate on the surface of the filter mesh, they are stripped off. Solid particles remain on the filter mesh, while the liquid passes through it. During the filtration process, as solid particles accumulate, the mesh openings gradually become clogged, increasing resistance. The ultrasonic vibration accelerates the movement of particles on the screen, speeds up solid–liquid separation, and improves filtration speed, thereby enhancing overall production efficiency and ensuring continuous online filtration of the machine.

Equipment Advantages

• High Filtration Accuracy: With the assistance of ultrasonic vibration, the machine effectively resolves clogging and adhesion issues caused by high-viscosity materials on the filter mesh, improving filtration accuracy and enabling the separation of finer particles.
• High-Efficiency Filtration and Screening: Ultrasonic vibration accelerates material movement on the filter mesh, increasing filtration speed and thereby enhancing overall production efficiency.
• Anti-Clogging Performance: The micro-vibrations generated by ultrasound disrupt the contact forces between particles, reducing the likelihood of mesh blockage. This is particularly suitable for processing sticky or easily agglomerated materials.
• Wide Filtration Range: The ultrasonic vibrating filter can be applied to a broad range of particulate materials, including fine particles, micro powders, viscous materials, and difficult-to-screen particles, meeting the filtration and screening requirements of various industries and applications.

Principle Introduction

The motor generates kinetic energy during operation, causing the machine body to vibrate and drive the material across single or multiple screen decks. The material is separated into different particle size fractions or impurities are removed from slurries. During the screening process, the material rolls across the screen surface, allowing it to pass through the mesh more smoothly.

The ultrasonic screen-cleaning system superimposes a high-frequency, low-amplitude ultrasonic vibration onto the screen surface. Ultra-fine powders are subjected to strong ultrasonic acceleration, keeping the material in a suspended state on the screen. This effectively suppresses mesh-blocking factors such as adhesion, friction, flattening, and particle wedging, thereby improving screening efficiency and screen-cleaning performance. It addresses screening challenges associated with strong adhesion, easy agglomeration, high static electricity, high fineness, high density, and low bulk density materials.

Equipment Advantages

• Suitable for separating difficult-to-screen materials in the 10–200 micron range; screening fineness up to 400 mesh
• Can be configured with 1 to 5 layers of screens with different mesh sizes according to material separation requirements
• Circular discharge outlet design with freely adjustable positioning, convenient for production layout
• Modular structure for easy assembly, disassembly, and cleaning
• Simplifies the separation of materials with special properties without altering their characteristics, making it especially suitable for new materials
• Elastic balls or ultrasonic screen-cleaning systems effectively prevent mesh clogging or near-size particle blinding, extending screen service life
• Low and stable operating temperature with no localized overheating, allowing continuous operation
• No special foundation required; compact footprint
