The underlying physics governing particle size obtained from a spiral jet mill were discussed in 1969 by Dobson and Rothwell who noted that output particle size could be estimated by opposing centrifugal and radial drag forces on a particle at the grind chamber exit. Theoretically, the spiral jet mill has a size of particle (d cut) that will remain balanced at the grind chamber exit with equal ...

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 continue milling particles above that size, resulting in a narrow size distribution of the resulting product.
