FIELD: metallurgy. SUBSTANCE: invention relates to design of rotary furnaces and it can be used for heat treatment of wet materials, mainly for calcination of aluminum hydroxide. In proposed installation containing rotary furnace, fixed gas conduit to let out gases consisting of coaxial branch pipe and vertical section and charging branch pipe for delivery of material, gas conduit to let out gases is connected with elbow placed inside housing of furnace, outlet hole of elbow being pointed upwards. EFFECT: reduced carry-over of dust and consumption of fuel. 1 dwg
