Operating technique of mills in the process of micronization milling of alumina
Апстракт
This paper summarized under the title: "Operating technique of mills in the process of micronization milling of alumina" is occupied with micronization of alumina and its influences on change of alumina crystal structure; the research is based on existing scientific and technical-technological findings and experiences in the field of development and application of processes of the materials. In short, this research task involves: - investigation of initial material effects on kinetics and mechanism of the particle formation together with the phase transformations occurring in the process characterization of materials, - consideration of close relations between theoretical principles of operation of high-energy mills, such as vibrational and planetary mills during the micronized of alumina which obeyed the certain laws, with their dependence on selected experimental conditions, - detailed investigation of the possibility to obtain high-grade αAl2O3 alumina in the form of Micronics, no a...gglomerated particles by the method of dry micronized combined with heat treatment, and starting from the γAl2O3 alumina modification after the Bayern process. The elements that are necessary for determination of operation of mills, particularly vibrational and planetary ones, were determined by detailed investigation of the alumina micronized also, conditions required to define the both technological and production parameters of micronization are fulfilled, too. Based on investigated parameters and theoretical consideration of the alumina micronized, together with its influences on change of the alumina crystal structure by usage of mills with advanced construction and contemporary instrumental techniques used in determination and observation of the most important physical chemical and thermic characteristics, kinetic model which is the basis for a quick and efficient determination of above parameters in order to optimize and atomize micronization processes was developed.
