Powder processing equipment for the production of battery anode materials

This series of air classifiers combine self-diffusion and centrifugal classification technologies, delivering both particle shaping and precise classification in one system.

Features

For high-end anode coke products, the classifier features an innovative design that allows for efficient fine powder removal. When producing Dmin≥2μm products, the process is completed in a single classification pass, avoiding the need for multiple passes. Other classifiers, both domestic and international, typically require two passes to remove -2μm fine powder, or if they manage to do it in one pass, they often suffer from low throughput and product yield
Ensures a high product yield while removing -2μm fine powder, delivering Dmin-compliant results without sacrificing output
Capable of handling large volumes of material, making it well-suited for producing narrow particle size distributions with D50=9-10μm
The system operates with 50% less installed power compared to other vertical and horizontal dry classifiers, while increasing classification efficiency by 40%
Offers precise cut points for large particles (D100), ensuring no oversized particles or residues in the final product
Capable of achieving high fineness with a 40% lower rotational speed compared to other vertical and horizontal classifiers, which not only boosts efficiency but also minimizes wear on the classifier wheel, particularly beneficial when processing materials with a Mohs hardness of less than 4.
Designed for large-scale production, with the LHB-T model capable of processing up to 100 tons per hour, making it the largest ultrafine classifier available today
