The relevance of the subject matter lies in the essential importance of belt conveyors in the technological processes of processing crops and the need to investigate their dynamic characteristics as the most important factor of trouble-free operation. This study aims to explore the design and movement principles of belt conveyors, utilized by agricultural enterprises for grain collection and transportation. The methodological approach is a theoretical study of the general principles of improving the design and operating parameters of a belt conveyor for working with contaminated grain. The results obtained indicate that there is a direct relationship between the belt conveyor's performance parameters on the one hand and the conveyor belt's width, speed of movement, and density of transported grain mass on the other. All the obtained dependencies were presented in the form of mathematical equations. The main types of belt conveyors that are used to work with grain crops were also identified, and a classification of such technical devices was presented. The list of standardised regulatory documents that regulate the technical conditions for the use of belt conveyors is taken into consideration. The main design and operational characteristics of belt conveyors, which are used to work with heavily contaminated grain, were also determined. The prospects for their improvement are determined to optimise technological operations for the collection and transportation of grain crops at enterprises in the Republic of Kazakhstan's agricultural sector. The practical significance of the results obtained lies in the possibility of their use in the development of belt conveyors designed to work with grain crops of a significant degree of contamination.
