Abstract
The article discusses the separation process efficiency issue of the fine powders in an air separator. The aerodynamic scheme of the air separator is proposed and the schemes of the gas-material flow through the elements of the separator gas-material path are considered. The equations of the gas-material flow motion through the separator gas-material path elements are proposed. The calculation of the air separator various operating modes is proposed. The results of an approximate graphical-analytical calculation of the gas-material path of the proposed aerodynamic scheme for the air separator are presented. A high convergence of theoretical positions with the performed experiments is shown.
Highlights
In the production of various building materials, their fine grinding is essential [1, 2]
Modern separators have a number of significant disadvantages, one of which is the insufficient efficiency of the separation process
The above gas-material path of the air separator contains two main elements - a tee, from one there is an exhaust of dusty air, and from the other supply of fresh atmospheric air
Summary
In the production of various building materials, their fine grinding is essential [1, 2]. In the production of cement, more than 50% of all consumed electricity is consumed for grinding [1, 6, 7]. To improve the quality of the cement produced, air separators are widely used, which improve the quality of the cement itself, and increase the technical and economic indicators of the entire production as a whole [8,9,10,11]. To increase the efficiency in [14] it is proposed to change the aerodynamic operating mode of the separator, which improves the operating modes of the air separator
