Podgorny Institute of Mechanical Engineering Problems of the National Academy of Sciences of Ukraine popup.description2  A cryomechanical grinding technique was developed and used to produce 16 types of test samples of non-oxidized powders for use as reference dust samples for quality studies of filter materials. The liquid nitrogen dispersion unit was commissioned and its operating modes were determined to obtain each of the types of powders. 16 types of non-oxidized powders were obtained, most of which have an average dispersion of from 1 to 5 microns. It is shown that the proposed technique can be used to disperse materials with different physicochemical properties. Product Description popup.authors popup.nrat_date 2020-04-02 Close
