Abstract
The current invention provides an improved jet nozzle suitable for use in a micronizing jet mill or retrofitting to an existing jet mill. The improved jet nozzle incorporates a coanda effect inducing element to enhance entrainment of particles to be ground within the vortex created by the micronizing jet mill. When the jet mill uses steam to generate the jet, use of the improved nozzle will reduce energy costs by increasing the efficiency of the jet mill.
