Learn About Jet Mill
Jet mills, or air jet mills, have a unique feature. They don’t require mechanical grinding tools. The particles crush and grind in a gas stream. They collide with each other repeatedly. Jet mills are an excellent choice in industry when ultra-fine grinding is required. They are suitable for dry and very hard materials and it is possible to achieve finenesses down to d97 = 1 µm with them.
Working Principle of Jet Mill
In a jet mill, compressed air enters the grinding chamber through special nozzles. The air is accelerated so much that it carries the particles along. The particles collide with each other many times, which breaks them down. A big advantage of this mill is that it has no mechanical grinding tools. This means the particles don’t touch anything, so there is no wear. This is why jet mills are excellent for very hard materials or materials that have to be as pure as possible. In a downstream cyclone separator or dust filter, the grinding gas removes finely ground material.
Jet öğütme, fason işleme şirketlerinin sunduğu önemli bir hizmettir. Parçacık boyutunu küçültme işlemidir. İlaç, kozmetik, boya, pigment ve endüstriyel kimyasallar gibi birçok sektör bu işleme ihtiyaç duyar.
This milling method uses high-pressure gas. It creates fast collisions between These collisions fracture the particles into smaller pieces.
Jet milling can reduce particle size and classify them in one step. These mills can finely grind friable materials including polymers, chemicals, and ceramics. Abrasive materials can be processed on this equipment without contamination.
A skilled tolling expert can optimize the jet milling process. This allows for achieving even smaller particle size ranges. Temperature-sensitive products can also do well.
Jet mills can even be used to blend some powders. Two or more streams of material can be fed into the mill, resulting in a homogenous blend.

Types of Jet Mills
Based on how they control the final particle size, jet mills are designed in one of two ways:
- Fluid bed jet mills feature air classifiers. These can be finely tuned to achieve the exact particle size and shape you need.
- Circular jet mills, or spiral jet mills, classify materials inside the grinding chamber.
Both mills are free of moving parts in the grinding chamber. This significantly reduces wear and tear on the equipment. It also makes cleaning and sanitization easy. This greatly reduces the risk of cross-contamination.
How Does Jet Mill Work?
The process doesn’t create heat like mechanical milling. So, softer powders and sensitive materials work well. Jet milling is a great choice when precision is important. It achieves uniform particle sizes, which is very appealing.
In circular and fluidized bed mills, jets of air or steam form from compressed gas. This gas has a gauge pressure of 50 to 120 psig. The most common gas used is commercially compressed air.
Superheated steam (392–980°F) can be compressed to 100–220 psig. This steam is useful for certain raw feed materials that don’t easily heat up. Some of the other gases used include:
- Azot, malzemeleri oksidasyondan ve/veya yangından koruyabilir.
- Argon, nitrojene göre daha pahalı olsa da, bir diğer inert seçenektir.
- Parçacıklar arasında daha yüksek hızlı çarpışma sağlamak için kullanılan helyum.
A great deal of energy is needed to create enough momentum to cause particles to break on impact. The compressor and nozzles change high air pressure into kinetic energy in the mill. Large particles recirculate, and multiple high-velocity collisions progressively reduce their mass.
At this point, the differences between circular and fluidized bed mills become clear. In a circular mill, small particles are less affected by centrifugal force. As they’re reduced in size, they migrate toward a central outlet in the milling chamber.
