The Fluidized Bed Jet Mill is an advanced ultra-fine grinding system designed for processing heat-sensitive, high-value and contamination-sensitive materials.
Unlike traditional mechanical grinding equipment, the fluidized bed jet mill uses high-speed compressed air to accelerate particles and achieve size reduction through particle-to-particle collision. Since there is no grinding media or mechanical contact inside the grinding chamber, the system provides excellent product purity and minimizes contamination.
JETER Fluidized Bed Jet Mills integrate grinding and dynamic classification technologies into one compact system, allowing precise control of particle size distribution and producing powders with excellent flowability and consistency.
The equipment is widely used in pharmaceutical micronization, battery materials, ceramic powders, fine chemicals, food additives and advanced materials where ultra-fine particle processing is required.
The working principle of a fluidized bed jet mill is based on high-speed airflow and particle collision technology.
During operation, compressed air enters the grinding chamber through specially designed nozzles, creating a high-speed airflow field. Raw materials are fed into the grinding zone and become suspended in the fluidized state.
Driven by the high-speed airflow, particles accelerate and collide with each other. The impact energy generated during particle collision breaks the material into smaller particles without the need for mechanical grinding components.
After grinding, the powder enters the classifier area. The dynamic classifier separates fine particles from coarse particles according to the required particle size.
Qualified fine powder is collected through the powder collection system, while oversized particles return to the grinding zone for further processing.
The final particle size can be accurately adjusted by controlling:
Air pressure
Feeding rate
Classifier speed
Material characteristics
This design enables stable production of micron and sub-micron powders with narrow particle size distribution.

The grinding chamber is the core area where particle acceleration and collision occur.
The optimized chamber design improves grinding efficiency while reducing material retention and contamination risk.
Multiple precision nozzles generate high-speed airflow jets that provide the required energy for particle acceleration and micronization.
The integrated classifier provides accurate particle size control.
By adjusting classifier speed, users can achieve different powder fineness requirements.
The feeding system ensures stable and continuous material supply, improving production consistency.
The collection system efficiently separates finished powder from airflow and provides a clean production environment.
The fluidized bed jet mill can achieve micron-level powder processing and is suitable for applications requiring strict particle size control.
Typical particle size range:
D50: 2-10 μm
D90: 10-45 μm
Because there are no grinding media or mechanical contact parts inside the grinding chamber, contamination risk is significantly reduced.
This makes the equipment especially suitable for:
Pharmaceutical ingredients
Battery materials
High-purity chemicals
Ceramic powders
The grinding process is driven by compressed air and generates minimal heat, making it ideal for heat-sensitive materials.
The integrated classifier allows operators to adjust powder fineness according to different application requirements.
The simple internal structure and stainless-steel design make cleaning and maintenance convenient, especially for GMP production environments.
The Fluidized Bed Jet Mill is widely used in industries that require high-purity, ultra-fine and precisely controlled powder processing.
Due to its low contamination, low temperature operation and excellent particle size control, it has become an ideal solution for advanced powder manufacturing.
