In conveyor transport systems, different solutions to the transfer points constructions are used. Choosing the right solution requires conditions analysis of the cooperation between two conveyors. For years, the analytical methods have been used to evaluate the discharge trajectory of the transported material. Increasingly, to evaluate the movement of grains in the transfer space to analyze the behavior of the bulk material in contact with transfer chute elements, researchers successfully use simulations performed in the discrete element method (DEM). Well-constructed chute allows the material stream to be uniformly fed onto the receiving conveyor with a desired stable tangential speed. Proper design reduces motion resistances and belt wear. In the paper, the analysis of selected construction solutions of transfer points and the possibilities of their usage in copper ore transport systems were performed. The research was conducted using the DEM simulations of the ore flow. For specifying the best conditions of the cooperation of the feeding and receiving conveyors, a series of simulations were generated. The criteria for the comparative evaluation of the analyzed solutions were the values of acceleration zone length and abrasive wear of the belt.
