ABSTRACT

The possibility of improving the technical and economic indicators of the technological process and equipment for the cement clinker making in rotary kilns by replacing the inclined cylindrical bodies of rotary kilns with screw bodies mounted horizontally is shown. The kinematics of motion of clinker particles in the screw body of a rotary kiln for the cement clinker making is analyzed and mathematical models of their motion inside the screw bodies are proposed. Examples of the created spatial forms of screw bodies of rotating furnaces with the use of the program complex "Compass-3D" are shown. Technical solutions protected by patents of the Russian Federation [1-9] are offered, and designs of bodies of the rotating furnaces are shown. The analytical study of the motion of the particles of cement raw mass is presented in the article, and output dependence to determine their velocity in a screw body of the rotary kiln have particular scientific and practical importance. In such furnaces, technical and economic advantages are achieved due to the longitudinal movement of the sludge pellets in a furnace for cement clinker making, the horizontal arrangement of the rotary kiln body and their counter flows, due to the fact that inside the entire length of the screw body, formed of a screw surface and helical grooves, which provide not only the movement of granules in the sludge, but also contribute to the intensification of the interaction of sludge granules for cement clinker making with each other and with the walls of the body, and this allows not only influencing the nature of the movement of sludge granules for the cement clinker making and expanding the technological capabilities, increasing the intensity of heat exchange, simplifying the operation of the rotary kiln at its horizontal location, expanding the technological capabilities, but also reducing the dimensions of the furnaces in length and their weight.
