Review article

The paper presents results of determining the parameters of experimental apparatus for investigation of mechanical activation processes and attrition of granular materials obtained on the basis of numerical experiment. The goal of the experiment was the determination of the influence pattern of oscillation parameters of the apparatus’ working tools on the process of volumetric deformation of the material layer and on dynamics of its vibration displacement. There have been obtained regression equations for calculation of normal reaction forces acting on the apparatus’ working tools in the stage of layer compression, durations of the layer compression stages acting and its flight, average velocity of transportation of the material layer and the value of maximum compression of the layer by working tools. There have been estimated the quantity parameters of the process of machining the material grains at developing the design of experimental installation and the technique of carrying out physical tests for full-scale research of the parameters of the machine processing of granular materials.
