The paper presents a concept of a technological line for the production of granulated fuel from RDF. The main assumption of the line is the complexity of processing a raw RDF with very variable input parameters (morphological and granulometric composition, proportion and type of impurities as well as variable moisture content) to a pellet with high quality parameters (specific density, mechanical durability). Based on an analysis of the raw material characteristics and preliminary research on the RDF granulation process, design guidelines and assumptions were proposed. This allowed to develop a block diagram including all technological operations which must be used to process raw material. For each operation a technical solution was proposed which best fulfills the stated assumptions. A vacuum transport system of raw material has been proposed to reduce the amount of fly dust generated during the production process. This system is equipped with a central filter from which the dust is driven for re-granulation. Such system, reduces production of waste byproducts. As the pelletizing unit, a developed by the authors pelletizer with modified dye was proposed. Thanks to this solution, the granulation process will proceed in the temperature about 100 °C. Beside recommended moisture content and fineness of the raw material, high temperature helps ensure the predetermined quality of pellets.
