This paper presents a dimensional and similarity analysis of a burnt pellet transfer chute for reproduction at a laboratory scale, using numerical simulation through the Discrete Element Method (DEM) to analyze the flow of granular material in the chute. The study begins with the presentation of the pellet production process, from beneficiation to pelletizing, burning, and storage, as well as the process and purpose of coating the pellets with glycerin and bauxite. Next, the study objects are presented, which are the conveyor belts that form the basis for the analysis condition, and the transfer chute, which is the object to be downsized to a smaller scale, followed by the presentation of the main components and constituent parts of both. The dimensional analysis and similarity for the chute are presented following the conditions and theories for it. Then we have the description of the granular material properties, which is useful for the numerical analysis, and the description of how the tests were carried out and the methodology for material characterization. The Bulk Flow Analyst software is discussed, as well as its simulations of material characterization and analysis of granular solid flow. As a result, we have the analysis of the prototype at a real and laboratory scale with the observation of the flow in the DEM numerical simulation performed, the results indicate the effectiveness of the transfer chute in the transport of burnt pellets.
