ANALYSIS OF THE RESULTS OF RESEARCH OF DEPENDENCE OF PRODUCTIVITY ON THE MAIN FACTORS OF VIBRATING-ROLLING GRINDER
Increasing productivity in grinding materials is a very urgent task. The authors examined the influence of the technological factors of the grinding process on productivity in an installation of completely new design. It is established that the most significant effect on the grinding process productivity is due to the factors such as gap size, relative rotation speed of the rolls and eccentricity value. A full factorial experiment was used in the study. The reproducibility of experiments at specified levels of variation has been mathematically proven with the Kohren criterion. The regression equation is received; it connects the parameters of the grinding process and productivity. The adequacy of the obtained mathematical model was verified with the help of the Fisher’s F -criterion. The response surface of the optimization criterion is represented by the graph to show the influence of factors on the optimization parameter.
