The paper presents the results of mixing elements of aftercrops, such as vetches and lupine, which differ as far as the dimensions and diameter of seeds are concerned. The research was conducted with the use of a laboratory mixer model for funnel flow system. The silos were equipped with inserts of RSI and double cone types. The research was conducted in four series, two runs with RSI inserts of two different diameters, a run with the double cone insert and, a run without application of any supporting elements. The assessment of quality of the mixture was carried out with the use of computer analysis of image acquisition. The results were analysed using one-way analysis of variance. The obtained results of the Fisher Test enable to reject the zero hypothesis and determine the impact of the elements used based on graphic interpretation. A significant influence of the double cone insert for improvement of the quality of mixture and greater stabilization of the mixing process supported with additional elements were noted. However, mixing without application of the inserts is characterized with violent run of the process in consecutive stages of mixing.
