Airflow pulverizers use high-velocity air or other gases to accelerate particles and generate repeated particle-to-particle impact, collision, and friction, allowing materials to be processed into very fine powders. Their grinding mechanism gives them a broad material range and makes them suitable for applications with demanding particle-size requirements.
Typical Applications
Airflow pulverizers can process a wide variety of materials, including:
- Hard and brittle materials: diamond, silicon carbide, and certain metal powders
- High-purity materials: ceramic pigments, pharmaceutical materials, and biochemical products
- Temperature-sensitive materials: selected pharmaceutical materials and PVC
For flammable, explosive, or oxidation-sensitive materials, the conventional air supply can be replaced with an inert gas such as nitrogen or carbon dioxide. This creates a controlled grinding environment and allows the equipment to perform pulverization and classification while reducing direct exposure to oxygen.
Main Characteristics
Airflow pulverizers are suitable for applications requiring fine particle sizes and can be used in large-scale chemical processing, mineral processing, and other industrial powder-production operations.
However, the process relies on a high-velocity airflow to accelerate and classify particles, so the air supply system can require relatively high power consumption. The complete system may also occupy more installation space because it typically includes auxiliary equipment such as compressors, separators, dust collectors, and fans.
For customers developing or maintaining airflow pulverizing systems, Hansheng Automation can provide custom precision machining based on customer drawings and technical specifications, including non-standard shafts, housings, mounting components, and other mechanical parts used in grinding and classification equipment.
