Jet Mill

Application Scenarios

Widely used in lithium-ion battery materials, ceramic materials, minerals, ceramic inks, coatings, food, beverages, pharmaceuticals, cosmetics, and more, this technology is ideal for grinding powder materials with high hardness, temperature sensitivity, and strict finished particle size requirements. It enhances the performance of cathode and anode materials.

Product Features

  1. Low wear: Predominantly, particles collide and rub against each other, resulting in minimal contact with the inner wall. This makes the equipment suitable for materials with a Mohs hardness of 9 or higher.
  2. High classification accuracy: The narrow particle size distribution range yields a particle size of up to d97 < 2μm, which is adjustable.
  3. Pollution-free: All components in contact with materials consist of ceramic or tungsten carbide-coated parts, eliminating metallic impurity contamination.
  4. Energy efficiency: Airflow crushers consume 30% less energy compared to other types (e.g., horizontal classifier type).
  5. Customizability: Inert gas can be employed for flammable, explosive, or moisture-sensitive materials, and closed-loop systems are available for recycling inert gas.
  6. Ease of maintenance: A top-driven flip cover design simplifies cleaning and maintenance tasks.

Structural Principle

In the case of airflow crushers, material particles enter the crushing zone within the container and are pulverized by the supersonic high-pressure airflow emitted from a nozzle. As particles collide and break down within the chamber, the crushed materials are carried by rising airflow to the classification area. The classifier wheel selects fine powder that meets particle size requirements, which exits the crusher through the outlet. Coarser powder is ejected by the classifier wheel and returns to the crushing area for further processing. This process continues until the desired particle size is achieved.
