Air Classifier
How It Works
Crushed mixed NCM powder is conveyed into the grading chamber through air transport pipelines. Secondary regulating air is introduced from the lower side to form a stable swirling airflow that evenly suspends NCM particles.
The central high-speed turbine wheel generates a powerful centrifugal field. Ultra-fine NCM particles flow through blade clearances with the airstream and are collected as finished products by cyclones and bag dust collectors. Dense NCM agglomerates carry great centrifugal inertia, collide against the chamber wall, slide downward and circulate back to the main grinding machine for regrinding.
Modulating turbine rotating speed and auxiliary air volume adjusts the classification cut point, which accurately controls NCM fineness and minimizes oversize particles to satisfy various specification standards of lithium battery cathode materials. For high-nickel NCM processing, the system supports inert nitrogen atmosphere operation to prevent surface oxidation.
Performance Features
Vertical Eddy Current Classifier — High-Throughput General-Purpose Type
Suitable for mass production of conventional industrial NCM (Nickel Cobalt Manganese) ternary cathode materials. Omni-directional uniform air intake fully disperses NCM particles, achieving high classification efficiency, low pressure loss, as well as low equipment investment and running cost. It serves as the mainstream matching equipment for dry processing lines equipped with air classifier mills for bulk NCM cathode material production.
Horizontal Turbine Classifier — High-Precision Ultrafine Type
Customized for high-end ultrafine NCM ternary cathode materials with D97 less than 8μm. Single-side air intake design and cantilever-mounted classification wheel form an extremely clear particle cut point with nearly no coarse residue left. It steadily produces narrow-size-distribution ultrafine NCM powder, perfectly matching high-purity, high-value scenarios including power battery, single-crystal high-nickel and high-end lithium battery cathode materials.
