ABSTRACT

To reduce the size and weight, increase productivity, simplify operation, reduce energy consumption in the cement production, the body is screwed and mounted horizontally. The technical solutions protected by patents of the Russian Federation are offered. Designs of body of the rotating furnaces, which, in comparison with known designs of similar purpose, are executed screw with internal screw surfaces, are shown. Technologies of assembly of screw bodies for single and serial production are offered. Over the past ten years, we have not only proposed design solutions to solve this problem, but also offered the opportunity to implement them into production. The development of technology of assembly of the screw body of rotary screw systems is presented in the article. Studies aimed to optimize the design parameters of the number of curved surfaces of the rotary kiln body are of particular scientific and practical importance. At the same time, the features of the proposed screw bodies include: (1) the area and shape of the cross-section of the screw bodies are different along the entire length from loading to unloading, which changes the speed and trajectory of the particles of the raw cement mass, expands the technological capabilities, increases productivity; (2) the design of the screw bodies allows providing for consistent discharge of raw cement mass particle flows during the transition from one section to the next as the flows move from the cold end of the furnace to the hot end, increase productivity and expand technological capabilities; (3) due to the mutually directed broken and smooth helical lines, the velocity vectors of the particles of the raw cement mass during transportation from loading to unloading change, which expands the technological capabilities; (4) along the inner perimeter of the screw bodies, broken or smooth screw surfaces are formed along their entire length, which provides a violation of the stationarity of the particle flows of the raw cement mass, increasing productivity and expanding technological capabilities.
