“…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].…”
