Jet Mill Classifier

The jet mill classifier is an ultra‑fine grinding and classification device specifically designed for lithium‑battery materials. Utilizing supersonic airflow impact coupled with centrifugal classification technology, it pulverizes raw materials to micron‑scale particle size, precisely controls the particle‑size distribution, and enhances the specific surface area and electrochemical performance of battery materials.

Product Highlights

Fully Ceramic Lining

Key components such as the grinding chamber and nozzles are constructed from zirconia or silicon carbide ceramic materials, completely eliminating metallic ion contamination and ensuring material purity ≥99.9%.

Inert Gas Protection

An optional nitrogen closed-loop circulation system prevents oxidation and degradation of lithium iron phosphate, with residual oxygen content ≤50 ppm.

Energy Consumption Reduced by 15–25%

Optimized airflow design (e.g., helical intake piping) minimizes over-grinding, achieving a specific energy consumption as low as 650–900 CNY/ton.

Precise Particle Size Control

Variable-frequency speed adjustment of the classifier wheel (500–3000 rpm) enables a particle size range of D50=0.6–75 μm, featuring a narrow distribution and an increase in tap density ≥0.1 g/cm³.

Fully Automated PLC Control

Real-time monitoring of pressure, temperature, and airflow parameters, with support for storing 50 formulations and remote integrated control.
