Pryadko N. The theory development of mineral fine grinding

IThe dissertation is devoted to the development of the theory and technology of mineral grinding on the connection basis of process technological and emission pa-rameters. Proceeding from the power feature analysis of mineral thin grinding in drum-type and jet mills the critical level of thin grinding power consumption is re-vealed, the experimental substantiation of fractions grinding independence mixture is carried out, balance, imitating, dynamic, stochastic models of thin grinding for identi-fication of technological grinding modes and increase of process efficiency are de-veloped. On the basis of the destruction theory and the application peculiar properties of an acoustic emission method for a counterflow jet mill the relations of technological and acoustic parameters are established. The mathematical cell model of process is developed on the basis of circuits Markov on the basis of acoustic monitoring results. Acoustic parameter of efficiency and an optimality criterion of jet mill operation are established. The opportunity of carrying out of mineral jet grinding optimization is shown on the basis of process acoustic monitoring results. Methods of grinding visu-alization and optimization with information technologies use are developed. It has al-lowed achieving required technological parameters at power consumption decrease and dispersion control observance.
