Air Classifier Mill – Long Cavity
How It Works
The lower part is an ultra-fine grinder, and the upper part is an ultra-fine classifier. The integrated design combines the dual functions of grinding and classification.
Materials are fed into the center of the grinding disc by a screw feeder, driven by the evenly distributed grinding blocks on the disc to disperse outward uniformly and gain acceleration. After colliding and grinding with each other in the grinding zone composed of the grinding disc and the gear ring, the materials enter the classification zone with the ascending air flow. Qualified fine powders are discharged through the classifier wheel, while coarser particles fall back to the grinding zone for further grinding.
The equipment enables materials to obtain greater kinetic energy, capable of producing finer powders. With a sufficient length of the ascending zone, it achieves excellent moisture evaporation effect, and the maximum particle size Dmax of the finished product can be accurately controlled with ease.
Performance and Features
Full Classification, Superior Fineness
With an extended classification chamber, materials undergo dual gravity and centrifugal classification. This high-precision process ensures superior fineness and exceptional control over large particles, resulting in uniform particle size distribution.
Extended Chamber, Efficient Dryin
The extended chamber creates an elongated path, maximizing contact between high-moisture materials and airflow. This enables efficient moisture evaporation during the classification process, achieving excellent drying performance.
Stone-on-Stone, Preserving Morphology
Utilizing the “stone-on-stone” principle, the equipment crushes materials via inter-particle impact to avoid morphological damage. It preserves the structure of needle-like materials, achieving an aspect ratio of 15:1 for special applications.
Wear-Resistant Material, Long Life
Core components are made of composite wear-resistant materials with excellent impact resistance. This effectively minimizes component wear, significantly extending service life while lowering maintenance frequency and costs.
