Ultrasonic vibrating screens have become an essential technology in the processing of ternary battery materials, such as NCM (nickel-cobalt-manganese) and NCA (nickel-cobalt-aluminum). These advanced materials, widely used in lithium-ion battery production, demand exceptional levels of purity, consistency, and particle uniformity. However, their complex physical properties make them extremely difficult to sieve using traditional methods.
Ternary powders often display characteristics such as:
Strong particle adsorption
High cohesiveness and tendency to clump
Sticky or viscous behavior
Electrostatic charge accumulation
High specific gravity
Extremely fine particle size
These traits lead to common screening issues like mesh clogging, reduced throughput, and material contamination—all of which can compromise the performance of the final product.
How Ultrasonic Screening Technology Works
The ultrasonic vibrating screen addresses these challenges by applying high-frequency ultrasonic vibrations (36KHz) directly to the screen mesh, powered by standard 220V, 50Hz electrical input. This ultrasonic energy:
Disrupts particle agglomeration
Minimizes powder adhesion and friction
Prevents mesh blinding
Enables smoother flow of ultra-fine materials
As a result, ternary powders that would normally stick together or block screen apertures are cleanly and consistently separated—greatly improving material purity and screening efficiency.
Core Advantages in Ternary Material Screening
1. Enhanced Product Purity
By efficiently removing oversize particles and foreign contaminants, the ultrasonic screen produces high-purity ternary powders, which are essential for high-performance batteries.
2. Effective Screening of Challenging Materials
The system is specifically designed to handle powders with:
High static electricity
Moisture sensitivity
Agglomeration tendencies
High-density particles
This makes ultrasonic screening a preferred method for sieving NCM/NCA cathode materials.
3. Noise Reduction and Clean Operation
Compared to conventional sieving machines, ultrasonic systems greatly reduce operational noise and maintain a clean, low-disturbance working environment, ideal for precision manufacturing lines.
4. Mesh Self-Cleaning Function
The continuous vibration keeps the screen surface clear of buildup, significantly reducing downtime and manual cleaning needs—leading to higher throughput and lower maintenance.
5. Non-Invasive and Material-Safe
Ultrasonic vibration is a non-contact, non-destructive process, ensuring that delicate or reactive materials are not altered during screening.
Transforming Ternary Powder Processing
The ultrasonic vibrating screen represents a major upgrade over traditional sieving equipment. It doesn’t just solve technical bottlenecks—it reshapes your production capabilities by offering:
Superior material handling
Higher processing efficiency
Consistent quality assurance
Lower operational noise and cost
