ABSTRACT:
A jet mill includes plural nozzle devices for discharging a composite stream of high velocity fluid. Each nozzle device includes a plural odd number of nozzle openings for discharging an individual stream of high velocity fluid. Each nozzle opening comprises (i) a converging region for converging and accelerating a volume of high pressure fluid; (ii) a throat region defining a narrowest diameter region of the nozzle opening; (iii) a first expansion region for producing a linear expansion of the volume of high pressure fluid, and (iv) a second expansion region for producing a turning expansion as well as a parallel flow of the volume of high pressure fluid. The first expansion region has a radius “r1” and a length “s1” with radius r1and length s1determined such that (dr1/ds1) is a constant. The second expansion region has a radius “r2” and a length “s2” with radius r2and length s2determined such that (dr2/ds2) is non-linear and a function of s2.
