Udara terkompresi atau uap super panas atau atmosfer inert lainnya memasuki pipa distribusi gas dari lubang injeksi gas umpan. Di bawah tekanannya sendiri, gas melewati beberapa nozel yang disusun secara tangensial di sekitar cincin dudukan untuk menghasilkan pancaran berkecepatan tinggi dan bertabrakan dengan material yang memasuki ruang penggilingan. Injektor pengumpan yang terdiri dari hopper, nosel pengumpan, dan tabung Venturi digunakan sebagai alat pengumpan. Bahan di dalam hopper dikeluarkan ke tabung Venturi melalui aliran jet dari nozzle pengumpan. Di dalam tabung Venturi, material dan aliran udara dicampur dan diberi tekanan dan masuk ke ruang penghancur. Material yang hancur dibawa ke tabung kelompok tengah melalui aliran udara dan melewati pipa tumpukan secara aksial ke dalam pipa knalpot tengah ke atas atau ke bawah ke dalam unit pengumpul.
Gas terkompresi digunakan untuk melewati pengumpan ejektor untuk membawa bahan mentah yang digiling ke dalam ruang penggilingan, dan didorong oleh aliran udara berkecepatan tinggi dari beberapa nozel, gas tersebut disemprotkan ke dinding penggilingan secara tangensial untuk mencapai efek penggilingan gesekan. . Dengan mengatur kedalaman memanjang ruang penggilingan, mengatur tekanan penggilingan atau kecepatan pengumpanan, kehalusan penggilingan dapat dikontrol. Dibandingkan dengan Spiral Jet Mill, pengendalian kehalusan penghancuran lebih sedikit.

By working with a tolling partner’s technical team, you will gain efficiency. They will help choose the best mill type. They will also pick the right speed and feed rate. They will also cover any special project needs.
The team brings focused insights and extensive experience to the table. However, you should also expect to provide safety data sheets and answer a few questions, such as:
A jet mill is a type of ultrafine grinding equipment. It is a machine that uses a lot of energy. Therefore, the feed particle size of the air flow mill should be as fine as possible. It is recommended that the feed particle size be less than 80 mesh. Under normal circumstances, the feed particle size needs to be less than 1 mm.
Jet milling usually makes particles that are 1 to 10 microns in size. This is referred to as micronization.
Some product formulations require particles as small as 200 nanometers. The material's properties determine how small these sizes can be. You can make them smaller by increasing the mill's power. Additionally, by increasing the time the material spends in the milling chamber.
Some products require particles larger than 10 microns. This can be achieved by reducing the power to the mill or increasing the feed rate to the equipment.
In both circular and fluidized bed mills, jets of air or steam are made by gas. The gas is compressed to a gauge pressure of 50 to 120 psig. The most common gas used is commercially compressed air.
Superheated steam (392–980°F) is compressed to 100–220 psig. It can also be used on raw feed materials that are not heat-sensitive. Some of the other gases used include:
Nitrogen, which can protect materials from oxidation and/or fire
Argon, another inert option, though more expensive than nitrogen
Helium, used to achieve higher-velocity impact between particles
A great deal of energy is needed to create enough momentum to cause particles to break on impact. The compressor and nozzles turn high air pressure into energy. They do this within the mill. Large particles recirculate, and multiple high-velocity collisions progressively reduce their mass.
