The analysis of the movement of the rock above the surface of the vibrating screen. According to theoretical studies have shown that the slope of the plane of the working surface of the screening has a significant impact on the effectiveness of screening. Based on the analysis of the motion of rocks on the surface of the vibration (active) screening developed a computer program for numerical and graphical simulation of particle motion relative to the screening surface, as well as statistical analysis of the results of multiple flight simulation particles at different parameters of the law of random fluctuations and values of the friction characteristics of the particles at impact . This program provides for the inclusion of the particle oscillation mode without sifting through the work surface noise. This mode will allow for each set of values of the parameters of the law to perform the work surface vibrations preassigned number of numerical experiments. An example of the trajectory of the particles on the moving screening surface obtained by the described program.
