Fluidized bed airflow mill is widely used in many industries, including chemical industry, mining, abrasives, refractory materials, battery materials, metallurgy, building materials, pharmaceuticals, ceramics, food, pesticides, feed, new materials and environmental protection. It is mainly used for ultra-fine grinding, breaking up and particle shaping of dry powder materials.
Advantages
The fluidized bed airflow mill has the following advantages:

Chemical industry: used to prepare ultra-fine chemical powder products.
Mining: used for ultra-fine crushing of ores.
Abrasives: used to prepare ultra-fine abrasives.
Refractory materials: used for ultrafine processing of refractory materials.
Battery materials: used for ultrafine processing of battery materials.
Metallurgy: used for ultrafine processing of metal powders.
Building materials: used for ultrafine grinding of building materials.
Pharmaceuticals: used for ultrafine powder processing of medicines.
Ceramics: used for ultrafine processing of ceramic materials.
Food: used for ultrafine grinding of food additives.
Pesticides: used for ultrafine processing of pesticides.
Feed: used for ultrafine processing of feed additives

The working principle of the fluidized bed air flow mill is to combine the reverse injection or counter-injection principle with the expanded gas jet flow in the fluidized bed. The specific process includes:
The material is fed into the silo through the star valve, and the screw feeder feeds the material into the crushing chamber or directly into the crushing chamber.
The supersonic jet generated by the rapid expansion and acceleration of the compressed air through the crushing nozzle forms a centripetal reverse jet flow field at the bottom of the crushing chamber, which fluidizes the material at the bottom of the grinding chamber.
The accelerated material converges at the intersection of multiple nozzles, resulting in violent impact, collision, friction and crushing.
The crushed material moves to the upper part of the crushing chamber with the rising air flow, and the coarse particles fall back to the lower part of the grinding chamber under the action of gravity, and the fine powder moves to the upper turbine classifier with the air flow.
In the flow field generated by the high-speed turbine, the coarse particles are thrown to the vicinity of the cylinder wall under the action of centrifugal force, and fall back to the lower part of the grinding chamber with the stalled coarse powder for further crushing.
The fine powder that meets the fineness requirements passes through the grading plate flow channel and is transported to the cyclone separator through the exhaust pipe as a product collection. A small amount of fine powder is further separated from the gas and solid by the bag collector, and the purified air is discharged outside the machine by the induced draft fan.
