The fluidized‑bed jet mill is a device that utilizes high‑speed airflow to perform dry‑type superfine pulverization. Driven by compressed air, raw materials are accelerated towards the intersection of four nozzles, where they are impacted and milled into powder. Subsequently, the milled powder is carried by the upward flowing air to the classifying zone.
Influenced by centrifugal force and airflow, the classified powder is separated and collected. Any remaining powder
1.No temperature rise꞉ The temperature remains stable during pulverization due to pneumatic expansion, ensuring that the milling cavity's temperature stays normal.
2.No contamination꞉ The entire process is contamination‑free, as materials are transported by airflow and milled through self‑collision and impact, eliminating the need for media involvement.
3.Durability꞉ Suitable for materials with a Mohs hardness of up to grade 9. The milling effect is achieved through the impact and collision among the particles rather than against the chamber walls.
4.Safe for flammable materials꞉ Inert gas can be utilized as a medium for milling flammable and explosive materials, enhancing safety.
5.Increased efficiency꞉ The capacity can be 5‑30% higher compared to older models, improving productivity.
1. The flowchart represents standard milling processing and can be customized according to customer requirements.
2. Regarding air resources꞉
A)For processing materials such as medicine and food, which require oil‑free air, an oil‑free air compressor will be provided. This eliminates the need for an oil remover.
B)For materials with less stringent requirements, a precise filter may be necessary, or in some cases, not required at all.
