Feb 14, 2020 The only large-scale rotary kiln plant for magnetic-reduction roasting was designed by Lurgi-Chonle, of Frankfurt, Germany, and built at Watensttev-Salzgitter prior to World War II. Lurgi reports that these 3.6-meter diameter by 50 meter long kilns were designed for a throughput of 800 tonsday, but actually achieved a throughput of 1150 tonsday.
We offer third generation tunnel kiln process from China, to convert soft iron ore lumps or briquetted iron ore fines into Direct Reduced Iron DRI. DRI or sponge iron is a high-quality metallic product and used as a feed-stock in the induction furnace electric arc furnace.
Clinkering process in rotary kiln To the most important factors influencing the clinkering process in rotary kiln are the following The composition of gas phase in the kiln depends on fuel composition and condition of combusting, which introduce to the kiln atmosphere CO2, HjO, CO and in minor share SO2 and NO. In this gaseous atmosphere are also the highly volatile components to which belong ...
Both hematite and magnetite ores can be used in the tunnel kiln. The process is more suitable for soft ores, such as blue dust. The tunnel kiln process can reach higher metallisation levels of 90-92, as compared to 86-88 in the rotary kiln. The first generation tunnel kilns used clay crucibles and the capacities were 10,000-25,000 tons per year.
Market share About 23 of sponge iron total production. 4 Tunnel furnace process . This process is the oldest direct reduction method. In this method, Thermal coal is mixed with iron ore as a reducing agent. Natural gas generates the required reduction temperature, and reduction is performed on Silicon Carbide SiC Crucibles in a tunnel furnace.

Nov 13, 2020 To reduce the accretion formation in DRI process, a more elaborate understanding is needed. In this context, we have reported a case study of 100 tons per day tpd rotary kiln Fig. 1 . The size of the kiln is 42 m length and 3 m outer diameter 2.6 m internal diameter, and inclination of 2.5 , resting on three support stations.
Although rotary kilns are designed to be used for driving a chemical reaction, an issue that often comes up in the processing of a material is when to draw the excess moisture from the feedstock.. Many times, there is an excess of moisture that needs to be removed from the material before it is converted in the rotary kiln, and people are faced with a decision buy another piece of equipment ...
