Jet Mill

Applications: Widely used for ultra-fine milling of materials in industries such as chemicals, pharmaceuticals, pesticides, refractories, abrasives, additives, flame retardants, electronic materials, AC foaming agents, carbon black, non-metallic minerals, and battery materials.

Operating Principle: Compressed air is filtered, dried, and dehumidified before being injected at high speed into the milling chamber through Laval nozzles. At the intersection of multiple high-pressure air streams, the material undergoes repeated collisions, friction, and shearing, leading to fragmentation. As the particles become finer, their mass decreases and the centrifugal force acting on them weakens, allowing them to enter the cyclone separator for collection. Particles that do not yet meet the size requirements continue to undergo collision and friction within the chamber until the desired fineness is achieved.

Key Features:

1. Feeding System: Utilizes a vibratory feeder for uniform, constant-speed, and stable material input, enhancing milling efficiency and increasing product yield.

2. Milling Chamber: Features a closed oval “racetrack” chamber design, enabling circulatory particle milling to achieve the target particle size and improve the qualification rate of the final product.

3. Cyclone Separation: A cyclone separation port is designed at the center of the milling chamber to isolate target products. It offers high grading precision, minimizes over-milling, and boosts output.

4. Unique Structure: The specialized design allows for tool-free disassembly, making maintenance convenient and fully compliant with GMP requirements.
