The purpose of the article is to carry out the synthesis by the method of hierarchical grouping by means of morphological analysis of screw conveyors with the possibilities of technological transformation and mobile change of the trajectory of material overload. The appropriate number of constituent elements of the conveyor structures and the relationships between them that determine their particular design features are determined. The basic analysis is based on a morphological matrix with the morphological features of the elements of the generated constructions of the screw conveyors and the connections between them. A considerable number of functional screw conveyor structures with separate types of functional operations or purpose, which are multifunctional and efficient compared to traditional screw conveyors, have been developed and investigated. The classification of screw conveyors with the possibility of technological transformation and mobile change of the trajectory of material overload is also developed. Structural synthesis of screw conveyors with the possibilities of technological transformation and mobile change of the trajectory of material overload by structural hierarchical grouping was performed by means of morphological analysis and a certain number of their variants was generated according to 9 types. It is also determined that individual technological operations or functional features, which are inherent in screw conveyors with the possibility of technological transformation and mobile trajectory change, can be combined into one design, which will allow to obtain multifunctional designs of conveyors.
