Air Classifier

This air classifier is a standalone dry grading unit customized for ATH (aluminum hydroxide) flame retardant filler deep processing, commonly matched with ring roller mills, air classifier mills and other ultrafine ATH grinding equipment. Fineness is precisely controlled via stepless adjustable turbine speed. It separates qualified fine ATH powder and oversized ATH agglomerates by centrifugal force, yielding finished ATH with narrow particle size distribution and stable performance for coatings, rubber, low-smoke halogen-free cable and electronic encapsulation ATH flame retardant fillers.

Air Classifier

How It Works

Technical breakdown of the core processes and technology behind Air Classifier.

Crushed mixed ATH 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 ATH particles.

The central high-speed turbine wheel generates a powerful centrifugal field. Ultra-fine ATH particles flow through blade clearances with the airstream and are collected as finished products by cyclones and bag dust collectors. Dense ATH 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 ATH fineness and minimizes oversize particles to satisfy various specification standards of industrial ATH flame retardant fillers.

Performance Features

Uncompromising performance and innovative design, optimized for high-efficiency production and durability.

Vertical Eddy Current Classifier — High-Throughput General-Purpose Type

Suitable for mass production of conventional industrial ATH flame retardant fillers. Omni-directional uniform air intake fully disperses ATH 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 ring roller mills for bulk ATH flame retardant filler production.

Horizontal Turbine Classifier — High-Precision Ultrafine Type

Customized for high-end ultrafine ATH with D97 less than 6μm. 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 submicron ATH powder, perfectly matching high-purity, high-value scenarios including electronic encapsulation, low-smoke halogen-free cable and high-end flame retardant ATH raw materials.
