fine grinding process in jet mill

  • Micronization in the pharmaceutical industry

    Jet mills. Until the introduction of jet mills in 1936 dry grinding in the subsieve range of 625 mesh (20 microns) to 2 500 mesh (5 microns) was impractical. To create fine particles with a narrow PSD manufacturers previously had to mill the material sieve out the oversized particles and re-mill. The process was long expensive and

       Jet Mills. A jet mill or fluid energy mill grinds material 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.
