Abstract

The mathematical description of the parameters of spatial movement processes of the grinding bodies and their interaction with the inclined intermediate diaphragm in the rotating body of the ball mill is carried out to determine the influence of inside mill devices on the grinding load. It allows defining the kinematic and dynamic characteristics for each of the grinding bodies and their groups; the calculating method of the power consumed by their movement. An analytical expression is obtained to calculate the power consumed by the grinding media motion in the mill body with inclined intermediate diaphragm. The numerical computer and physical experiments with mill without inside mill devices are conducted to determine the power consumed by the grinding media motion. A quantitative estimation of the changes of kinematic parameters during the grinding media rotation, characterized by more intensive movement and changing their mode installation of the inclined intermediate diaphragm which contributes to the intensification of the process of grinding material is given.
