Bases of Increasing Operational Characteristics of the Equipment for Cement Production

“…For example, figure 1 shows one of the proposed designs of a rotary kiln with a horizontal axis of rotation of the screw body, the novelty of which is confirmed by patents of the Russian Federation for inventions [2][3][4][5][6][7][8][9][10]. Therefore, the development of technology for the manufacture of screw bodies and optimization of their design parameters is a timely, relevant task and allows planning and implementing an innovative way of cement production development, reducing energy costs, improving technical and economic indicators [10][11][12][13][14][15][16][17][18][19][20][21][22][23].…”

Processing Equipment on the Basis of Operative Parts in the Form of Screw Rotors With Profiled Perimeter

“…Change of perimeter shape of external and internal rotor surfaces allows to expand technological capacities of processing equipment and to provide increase in efficiency of processing due to increase of its amplitude-frequency characteristics [7][8][9][10][11][12]. As to the peculiarities of operative bodies in the form of screw rotors with shaped perimeter, their internal cavity represents a wavy form created from the sides of semicircular form.…”

Investigation of the Movement of Cement Clinker Particles in the Screw Body of a Rotary Kiln for Its Making

“…The consequence of this is: significant energy costs due to the large size, limited technological capabilities, complexity of operation and a large mass of rotary kilns. To eliminate these shortcomings, technologies and equipment based on screw bodies with a horizontal axis of rotation are proposed, which allows outlining and implementing an innovative way of development of cement production, reducing energy costs, improving technical and economic indicators [10][11][12][13][14][15][16][17][18][19][20][21][22].…”
