Justification of the air separation curve

Abstract

The article considers a method for increasing the production efficiency of fine powders. It is shown that modern air separators do not have high efficiency. A method for increasing the efficiency of air separators is proposed. It is noted that the main characteristic of the separation process is the separation curve, with the help of which a dispersed composition of fine and coarse products can be found. The calculation is made taking into account the turbulent diffusion of separation air in the casing of the air separator, and also the constructive features of the separator in question. The separation function is proposed taking into account the proposed technical solution.

“…In the production of cement, more than 50% of all consumed electricity is consumed for grinding [1,6,7]. At the same time, to improve the quality of the cement produced, air separators are widely used, which not only improve the quality of the cement itself, but also increase the technical and economic indicators of the entire production as a whole [8][9][10][11]. However, modern separators have a number of significant disadvantages, one of which is the insufficient efficiency of the separation process.…”
