Jet Milling And Particle Classfication

Jet milling is the term commonly applied to fluid energy milling. It is a process utilizing the potential energy of a compressible fluid and converting it to kinetic energy within the mill grinding chamber. This occurs when compressed gas is injected through specially designed nozzles. As the gas exits the nozzle it rapidly expands and creates ...
