The jet mill is the most suitable system for the micronizing of
chemical and pharmaceutical products.
Product particles are fed into the milling chamber through a
Venturi injector.
High-velocity air, or nitrogen, is introduced into the mill through
jet nozzles placed around the circular chamber. Particles,
accelerated inside the milling chamber, are dragged in a vortical
movement causing these to collide repeatedly and to be reduced
to small dimensions. The exhausted flow carries micronized
particles into a suitable cyclone-filter where it is dedusted through
a set of filtering bags and discharged to the outside. Micronized
product collection takes place into the bottom hopper of the
cyclone-filter.
