Cleaning and sorting of agricultural materials are the essential processes in agricultural production. Many researchers have carried out important work on the study of optimizing the parameters of grain cleaning machines. One of these parameters, affecting the quality of machine, is the grain material outflow characterized by patterns of input velocities into the separation zone. The article describes the advantages and disadvantages of methods for determining the rate of grain material outflow expiration. Here is shown the model of heterogeneous bulky environment of outflow from the hopper with a lateral outlet in a software complex EDEM Simulation. The analysis of the obtained results with the use of contact model Hertz-Mindlin (no slip) with RVD Rolling Friction has demonstrated a significant sparseness of grain material outflow velocities in a steady state of 0,61 m/s to 0,72 m/s with an average 0,687 m/s for the specified parameters of a grain cleaning machine. The described method can be used to solve the problem of determining the rate of expiration of grain material in the design of grain cleaning machines with the subsequent optimization of their operation.
