Air Classifier Mill

The Air Classifier Mill is an integrated dry-process ultrafine de-agglomeration system combining impact dispersion with built-in dynamic air classification. Widely deployed for precipitated silica processing — it is the most commonly used mass-production model in the industry — it delivers stepless fineness adjustment, narrow particle size distribution and exceptional agglomerate breakdown capability. An optional ceramic-lined grinding chamber minimizes metal contamination, safeguarding the high purity critical to silicone rubber, food-grade and coating-grade silica. The mill can be seamlessly integrated with precision classifiers, closed conveying systems and surface modification equipment to form a complete closed-loop silica production line.

Air Classifier Mill

How It Works

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

Spray-dried silica powder feeds into the grinding chamber via the feed valve, where high-speed rotating impact discs apply controlled impact, shear and collision forces to effectively disperse spray-drying derived hard agglomerates while precisely regulating particle size distribution and strictly controlling D50 / D90 oversized particles. Airflow conveys the processed particles upward to the integrated turbine classifier. Fine silica powder meeting specification passes through the classifier and is collected by cyclone separator and bag dust collector, while oversized coarse particles are centrifugally returned to the grinding chamber for reprocessing, creating a continuous closed-circuit cycle. An optional water-cooling jacket for the grinding chamber supports temperature-sensitive processing requirements — particularly critical for high-dispersion and hydrophobic silica grades — preserving stable powder morphology, bulk density and BET surface area while preventing thermal degradation of reinforcing performance.
