Air Classifier Mill

To meet the carbon black industry’s stringent grinding requirements of residual impurities <5.0 ppm on +325 mesh and <30.0 ppm on +500 mesh, we have developed specialized grinding equipment based on the proven JCSM-V and JRTM models. Our separate shaft and independent bearing housing design effectively dissipates heat generated during high-speed processing, preventing Recovered Carbon Black (rCB) from sticking or coking due to temperature rise, thus ensuring consistent material quality and 24/7 continuous operation. With a full range of models available, we deliver customized, heavy-duty solutions tailored to diverse industrial production capacities.

Air Classifier Mill

How It Works

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

The machine features a vertical cylindrical design, integrating an ultra-fine grinding mill at the base with a high-precision air classifier at the top. The grinding chamber pulverizes various pyrolysis chars into fine powder to achieve optimal de-agglomeration, effectively releasing primary carbon black particles from the mineral matrix. This powder then rises to the grading chamber, where a high-speed impeller separates it: high-purity rCB particles are discharged for collection, while oversized powder is automatically redirected to the grinding zone for further processing.

Both the grinding disc and classifying impeller are powered by independent driving systems, with variable speed control on the impeller to allow for precise adjustment of D90 < 10μm fineness and purity levels. A specialized screw feeding system ensures uniform material input, with the feed rate fully adjustable via frequency control to maintain optimal balance between throughput and separation efficiency.

Performance Features

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

Forced Circulation for Coarse Particles & Ultra-Low Residue

Equipped with a specialized external circulation pipe and an integrated Venturi tube, the system generates powerful suction to enforce continuous recirculation of coarse particles. This design strictly eliminates bypass, satisfying the most stringent residue control standards to guarantee absolute purity in high-cleanliness environments.

Widened Hammers for Enhanced Impactor Power

The model features an engineered, widened hammer geometry that maximizes the material contact area and amplifies impact forces. While strictly preserving particle uniformity, it significantly accelerates breakdown efficiency, making it ideal for traditional high-fineness processing.

Precision Parameter Control for Mainstream High-Standard Applications

By delivering exact control over core operating parameters, the system offers exceptional versatility. It reliably meets the premium purity and particle sizing benchmarks demanded by mainstream industrial applications, empowering enterprises to achieve standardized, highly efficient production.
