Lithium Carbonate Powder Screening Challenges: Navector Ultrasonic Screening System

Against the backdrop of the rapid development of the new energy industry, lithium carbonate, as one of the core raw materials of lithium batteries, continues to see growing demand. As an important precursor of cathode materials, the particle size distribution, purity, and stability of lithium carbonate powder directly affect the quality of subsequent material preparation.
In actual production processes, lithium carbonate powder needs to undergo a screening process to achieve particle size control and impurity removal. However, due to the characteristics of fine particle size, easy agglomeration, and moisture absorption, problems such as screen clogging, low screening efficiency, and unstable accuracy are very likely to occur during the screening process.

These issues can lead to the following impacts:
Reduced screening efficiency
Uneven particle size distribution
Decreased product consistency
Increased production costs
Higher equipment maintenance frequency

Therefore, how to solve the clogging problem while ensuring screening accuracy has become a key technical challenge that lithium carbonate manufacturers must address.

I. The Importance of Screening in Lithium Carbonate Production
In the production of lithium carbonate, the screening process is mainly used to control product particle size, remove impurities, and ensure powder uniformity.

 Particle Size Distribution Control

The particle size of lithium carbonate powder directly affects the synthesis performance of subsequent cathode materials, such as:
Reaction uniformity
Sintering performance
Electrochemical performance
A stable particle size distribution is the basis for ensuring consistent product quality.

 Removal of Agglomerated Particles

During drying and storage, lithium carbonate powder tends to form agglomerates, which can affect the stability of subsequent processes.
Screening can effectively remove abnormal particles and ensure powder uniformity.

 Improvement of Product Purity

The screening process can remove impurity particles, improve product purity, and meet battery-grade material requirements.

II. Causes of Lithium Carbonate Screening Problems
The difficulty in screening lithium carbonate powder is mainly determined by its physical properties.

Fine particle size
The particle size of lithium carbonate powder is usually in the tens of microns range, which can easily approach the mesh size, causing blockage.

Easy agglomeration
There is strong adhesion between fine particles, making them prone to forming agglomerates.

Strong moisture absorption
Lithium carbonate has certain hygroscopicity and tends to adhere under high humidity conditions.

Poor powder flowability
Irregular particle morphology leads to uneven distribution on the screen surface.

III. Key Technical Challenges in Lithium Carbonate Screening
The screening process of lithium carbonate usually faces the following technical challenges.

High anti-clogging requirements
Fine powder easily blocks mesh openings, requiring efficient anti-clogging technology.

High-precision classification requirements
Stable processing capacity must be maintained under high screening accuracy conditions.

High screening stability requirements
Continuous operation is required during production, with minimal fluctuations in screening performance.

Environmental adaptability requirements
The system must adapt to production environments with varying humidity levels.
