The article is devoted to the analysis of ways to increase the energy efficiency of sand drying. Energy-saving measures in drying plants are considered. Since 90% of all drying plants are convective, it is recommended to consider the issues of increasing energy efficiency in installations of this type. It is proposed to increase the energy efficiency of the drying process due to partial recycling of the spent drying agent. The use of this method will allow Millerovsky GOK in Millerovo, Rostov region to reduce fuel costs by 10%.

In this article, the possibilities of saving thermal energy in Millerovsky GOK JSC, Millerovo, Rostov region, due to the recycling of the drying agent were considered. The drying process was constructed on an hd diagram of moist air, the parameters of the characteristic points of the drying agent without and with the recirculation of the drying agent were determined. A possible reduction in the heat output for drying by 17% has been revealed.
