The paper considers the modelling of the finely-dispersed non-coherent material flowing from the conic unloading hopper hole under the vibration disturbance of the flow with the conical bottom. There was presented the method for bringing Navier-Stokes equations that describe the movement of the non-coherent material under vibration, to the Lorenz model, based on which there were received graphic dependences, which allow forecasting the behavior of non-coherent material at the equipment projecting stage and controlling it by means of vibration intensity change as well as the unloading hopper hole parameters.
