FIELD: drying technologies.
SUBSTANCE: invention relates to a process for drying fine materials, such as fine-grained coal, crushed stone, sand, etc. A method for drying finely dispersed materials, which consists in supplying a heat carrier in countercurrent to the movement of the material, and recirculated air with a temperature of 110-120 °C and a relative humidity of not more than 3% is used as a heat carrier, which, after the drying chamber, is first dried from the heat pump evaporator, then heated in the heat pump condenser and fed back to the drying chamber.
EFFECT: increased energy efficiency of drying fine materials.
