Jet mill Wikipedia

A jet mill consists of a short cylinder, meaning the cylinder's height is less than its diameter. Compressed gas is forced into the mill through nozzles tangent to the cylinder wall, creating a vortex. The gas leaves the mill through a tube along the axis of the cylinder. Solid particles in the mill are subject to two competing forces:

Jet mill Wikipedia

网页A 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 continuing to mill particles above that size, resulting in a narrow size distribution of the resulting product. Particles leaving the mill can be separated from the gas stream by

Chapter 8 Air Jet Milling ScienceDirect

网页2007年1月1日Projecting one jet of particles against another is one way to overcome the problem of wear on the impact anvil. This method was introduced by Willoughby in 1917 [8] and is the basis of the Majac mill. The feed product is swept round the grinding chamber and through the two phase (air+particles) nozzles to impact each other until the particles

网页ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materi-als become very abrasive; therefore, they are not suitable for high-speed hammer mills. In a typical jet mill, grinding action is caused mainly by particle-particle collisions, so wear to the mill’s internals is less of an issue.
