Pellet Plant (KOBELCO Pelletizing System)
KOBELCO Pelletizing System
Features of KOBELCO Pelletizing System
In 1966, Kobe Steel obtained a license for the Great Kiln process from Allis-Chalmers and developed the current KOBELCO Pelletizing System as its own exclusive technology.
The Great Kiln process utilizes a rotary kiln in the induration area, which decreases uneven pellet firing compared to other systems and facilitates the production of high-quality pellets.
The KOBELCO Pelletizing System exhibits its strength, incorporating Kobe Steel's extensive experience and know-how:
- Utilizing Kobe Steel's know-how as a pellet plant supplier and as a pellet manufacturer operating a pellet plant at its Kakogawa Works.
- Capable of designing optimal pellet plants from the user's perspective, leveraging the experience of using pellets as a raw material in blast furnaces at Kakogawa Works as well as in direct reduction (DR) plants overseas.
- Our delivery record includes the world's largest grate-kiln pellet plant using 100% hematite ore, with an annual production capacity of 6 million tons.
We implement optimal process design based on sample testing to provide reliable plants capable of producing high-quality pellets. Customers from around the world have been praising our expertise in building highly-efficient pellet plants, as well as our exceptional technical assistance and after-sales support.
Together with our subsidiary Midrex Technologies, Inc., a leading company in the direct reduction ironmaking process, we can provide pellet and DR plants in package form, as well as seamless solutions tailored to customer needs, encompassing pellets as raw materials to direct reduced iron (DRI).
