METHOD OF GRINDING OF POWDER REFRACTORIES
The article describes experimental researches connected with evaluating the burnishing’s influence on the structure of grinded products which are acquired by using the method of self-propagating high-temperature synthesis. Examples such as grinding of titanium diboride and aluminum nitrite show that the introduction of burnishing operation of synthesis products in the rollers of a fabrication mill may lead to formation of intersecting slipping areas in the powdered particles that have a weakened adhesion strength, which provides further grinding of synthesis products in a ball mill. It is also explained that a similar result could be achieved in case of derivation of circumferential speed of the rollers during the burnishing process; in addition to that the time of synthesis products’ grinding decreases at one degree in comparison to a ball mill.
