Jet Mills | Hosokawa Alpine
Jet mills (also called air jet mills) have a special feature: they do not need mechanical grinding tools. Instead, the particles are crushed and ground in a gas stream by repeatedly colliding with each other there. Jet mills are an excellent choice in industry when ultra-fine grinding is required.
Compact Jet Mill with Speed 50 - 500 g/hr - MSK- BPM-50
MSK- BPM-50 is a lab scale jet mill with 50 - 500 g/hour output sped. The jet mill grinds materials by using a high speed jet of compressed air or inert gas to impact particles into each other. Jet mills can be designed to output particles below a certain size, while continue milling particles above that size, resulting in a narrow size distribution of the resulting product.
Jet mill working principle - Jet Mill | Air classifier mill
Jet mills operate in compressed air, gas or high pressure superheated steam. Jet mills have no moving parts, thereby eliminating contamination due to contact with external grinding media. It is also an ideal process to grind heat-sensitive and waxy material because no attritional heat is generated. Jet mill works on fluid energy.

Miniaturization of Particles by Jet Milling with ...
Micronization is the miniaturization of particles by jet milling with compressed air or other gas to a range of 2-200 microns (µm). For most dry grinding processes, 2µm is the practical limit of the technology. Nanonization is the miniaturization of particles by jet milling with superheated steam. By using superheated steam as the grinding ...

Steam jet mills are a type of jet mill used in dry grinding devices. Instead of compressed air, superheated steam (pressure ≥0.2 MPa, temperature ≥200°C) is applied as the grinding energy source (Zhang & Chen, Reference Zhang and Chen 2018). Compared with the conventional jet mill, the steam jet mill has the following characteristics.
Chapter 8 Air Jet Milling - ScienceDirect
Air jet milling, or more correctly fluid energy milling, uses high velocity jets of gas to impart energy to particles for size reduction. Albus gives a brief history of air jet mills. The first versions, developed in the late 19th century, used a jet of compressed air to project solids against a target.
