The Brief Application of Rotary Kiln Pellet Technology

Rotary kiln pellet technology is a pelletizing process adopting chain grate machine dry, preheating pellet, rotary kiln consolidation, roast pellets, cooling finished pellets by ring cooler. Rotary kiln belongs to building material equipment. It can fire raw material grinded by grinding mill equipment into clinker at a very high temperatures of rotary kiln. It is said that the rotary kiln is the main cement equipment in cement production process, so it is also called cement kiln. Meanwhile, the rotary kiln can be used as metallurgical equipment in metallurgy chemical industry and calcinating non-ferrous metals, concentrates, crude ore, intermediate, calcined lime and dolomite, etc.

Pellets produced by this technology is a high quality blast furnace raw material with high grade of iron and good metallurgical performance which is suitable for the commercialization advantages of long period storage and long distance transportation. With the use of sinter, it can effectively reduce blast furnace coke rate and improve the blast furnace production to make blast furnace reasonable. It has advanced craft, can make full use of secondary energy and clean environment. The pellet has high quality, low consumption, good economic and environmental benefits. But the technology of furnace pellets, uneven pellet quality, poor adaptability to raw materials which is more difficult for mass production. According to the status and characteristics of steel and mining enterprises,small and medium grate - kiln pellet production line is rapidly developed due to the advanced technology, practical use, low investment, fast construction and good benefits.
