Abstract
This invention relates to a device for the heat treatment of fine material, including a rotary tube furnace, a multi-stage pre-heater heated by the exhaust gases from the rotary furnace and a zone through which the exhaust gases flow and provided with rotary lifting members, with the material extracted from the second stage of the pre-heater being fed into said zone before it is fed from the furnace exhaust gases from the first stage of the pre-heater and then reaches the rotary tube furnace.
