Outlook for using modern rotary screw systems in industry

Abstract

The use of rotary screw systems began in the 30s of the XX century as they were part of the emerging military industrial complex. Currently, rotary screw systems are used in a number of sectors of the national economy (in mechanical engineering, in the food industry, in gas and oil production, applicable in such industries as oil refining, chemical industry, agriculture, building industry, construction, etc.). However, the scale of their application is not commensurate with the benefits they provide compared to other types of systems, the functioning of which is based on different technological principles. The paper presents an outlook on the introduction and use of technology and equipment in industry, which will use the original designs of rotary screw bodies with a horizontal arrangement of the rotation axis as working bodies, which will reduce energy costs, improve technical and economic indicators, simplify maintenance and increase productivity. The paper presents the perspective of the use of rotary screw systems in the industry using the example of the cement industry on the example of a design of a furnace with a grate cooler for the clinker production. The proposed design has great scientific and practical significance, which is confirmed by the obtained patents. The presented technology for manufacturing screw bodies and optimizing their design parameters allows outlining and implementing an innovative way to develop cement production. As the results of our research, we not only developed the technology of assembling screw bodies for single and serial production, but also performed work on optimizing their design parameters.
