Powder Wet Vibrating Screen System For Lithium Battery Material Testing

The Powder Wet Vibrating Screen System is designed for particle size separation and distribution analysis of lithium battery materials under wet conditions. The system combines controlled vibration with liquid-assisted sieving to accurately classify fine powders and slurry-based materials. It is suitable for quality control, formulation verification, and process optimization of electrode materials and functional powders used in lithium-ion battery manufacturing.

Application

(1) Wet particle size distribution (PSD) analysis of lithium battery cathode and anode materials.

(2) Classification and screening of slurry-based powders containing solvents or binders.

(3) Quality consistency evaluation of active materials, conductive additives, and ceramic powders.

(4) Agglomeration and dispersion assessment during material development and scale-up.

(5) Incoming inspection and batch-to-batch comparison of battery raw materials.

(6) Laboratory and pilot-scale material research for lithium-ion and solid-state batteries.

Standards

(1) ASTM E11 – Standard Specification for Woven Wire Test Sieve Cloth and Test Sieves.

(2) ISO 3310-1 – Test Sieves – Technical Requirements and Testing – Metal Wire Cloth Sieves.

(3) IEC 62660-3 – Secondary Lithium-Ion Cells – Safety Requirements (reference application).

(4) RoHS – Restriction of Hazardous Substances Directive.

(5) CE Certification – Conformité Européenne.

Features

(1) Wet sieving design suitable for fine powders and slurry-based materials.

(2) High-precision vibration control for stable and repeatable particle stratification.

(3) Anti-clogging structure supporting continuous wet screening.

(4) Corrosion-resistant construction for use with acidic, alkaline, and organic solvents.

(5) Multi-layer sieve stack enabling simultaneous multi-size classification.

(6) Integrated control system for standardized and repeatable test operation.

(7) Low-noise operation suitable for laboratory environments.

(8) Safety-oriented design with emergency drainage and protective enclosures.

(2) Secure the sieve stack and connect the wet circulation or drainage system.

(3) Add the powder sample and appropriate liquid medium to the top sieve.

(4) Set vibration amplitude, frequency, and test duration.

(5) Start the system and perform wet sieving until completion.

(6) Collect retained and passed materials from each sieve for analysis and reporting.

Maintenance Information

(1) Clean sieves, drainage lines, and contact components immediately after wet testing.

(2) Inspect sieve mesh integrity regularly to prevent measurement deviation.

(3) Verify vibration amplitude and frequency calibration at scheduled intervals.

(4) Check sealing components and corrosion-prone parts for wear.

(5) Store sieves and accessories in a clean and dry environment after use.
