Abstract

In the article the actual scientific and practical problem of creation of the universal mathematical model of dynamic processes in the shockless model of the ball mill is solved. This allowed to determine the technological qualities of the device and to make an effective choice of its rational parameters. Computational studies have been carried out using the developed model by means of computer calculations. As a result, important regularities of the influence of parameters on the technological indicators of the technological device have been established. The result of the study is the first development of a nonholonomic mathematical model of dynamic processes in a ball mill, presented in the form of Gibbs-Appell equations. It is shown that the calculation of the acceleration energy and the formulation of the equations of motion are significantly simplified when quasi-accelerations are used instead of generalised acceleration equations. The developed mathematical model allows to calculate the trajectories of the contact point of the ball with the surface of the spherical chamber, the compressive forces of interaction with the surface of the shell. The results of the mathematical modelling allow efficient selection of rational parameters of the process equipment from the technological point of view.
