The article is devoted to the study of the influence of the loading method on the productivity of a spiral-screw conveyor - one of the most common types of equipment for moving bulk materials in agricultural production, food and processing industries. The principle of operation of screw conveyors is considered, which is based on the movement of the load along the transport channel under the action of a rotating working body due to the dragging of the material along the inner surface of the casing, regardless of the physical and mechanical properties of the load. The features of the functioning of slow-speed and high-speed screws are analyzed, the influence of the screw rotation frequency, winding pitch, working body diameter and conveyor inclination angle on the nature of the movement of material particles and the productivity of the system as a whole is established. It is shown that in slow-moving screws, particles move mainly translationally, while in high-speed ones, their trajectory is complicated by centrifugal forces.
Particular attention is paid to the comparative analysis of loading methods - gravitational and forced, as well as kinematic schemes of material supply: axial, angular and circular. It is shown that the shape of the loading hopper significantly affects the uniformity of cargo supply and the conveyor productivity coefficient, the value of which can vary from 0.62 to 1.00 depending on the design of the hopper. It is established that the use of a circular loading chamber increases the conveyor productivity by 6–23%, and the use of feeders - by 1.7–3 times. Theoretical dependencies are given for determining the critical angular velocity, productivity and drive power of the screw conveyor, taking into account the design and operating parameters of the screw.
The electromechanical system of the conveyor is considered as a single complex "loading device - screw - electric drive", in which the change in resistance to material movement depending on the loading scheme is directly reflected in the loading characteristics of the drive asynchronous electric motor and its operating modes.

Technology, energy, agriculture transport AIC is a scholarly professional journal with a long-standing history and stable academic tradition, reflecting the evolution of engineering and technical sciences within the agro-industrial sector of Ukraine.
The journal was founded in 1997 under the title Bulletin of Vinnytsia State Agricultural Institute. According to the Resolution of the Presidium of the Higher Attestation Commission of Ukraine dated September 11, 1997, the publication obtained the status of a professional scientific journal, which enabled the publication of the main results of doctoral and candidate dissertations in technical sciences. From its inception, the journal positioned itself as an academic platform for addressing current issues of mechanization, electrification, and technical support of agricultural production. During 2001–2014, the journal was published under the title Proceedings of Vinnytsia National Agrarian University. Series: Technical Sciences (State Registration Certificate of Print Media KV No. 16644-5116 PR dated April 30, 2010). Throughout this period, a systematic approach to the selection and peer review of scientific manuscripts was established, the thematic scope of publications was expanded, and continuity of scientific directions as well as the development of sectoral engineering schools was ensured. Since 2015, the journal has been published under its current title, Technology, energy, agriculture transport AIC (State Registration Certificate No. 21906-11806 R dated March 12, 2016). The change of title reflected the expansion of the journal’s thematic coverage and its orientation toward interdisciplinary research in mechanical engineering, energy systems, electrical engineering, transport technologies, automation, and digital solutions for the agro-industrial complex.
