FIELD: metallurgy, chemical, food and other industries. SUBSTANCE: furnace for heat treatment of noncaking loose materials has drum with rotary rotation drive, heating devices, heat insulation and material changing and discharging units. Heating devices are made in form of heating elements installed coaxially inside drum whose inner surface is furnished with spiral-shape insert, height of spiral member being not less than 1/3 rd of drum inner diameter. EFFECT: increased efficiency of heat treatment of loose material owing to intensification of heat exchange, increased furnace output. 1 dwgi |
