With the development trend of high-end, green and intelligent steel industry, the global requirements for hematite and whole hematite roasting are getting higher and higher, and higher requirements are also put forward for pellet production equipment. Pellet production enterprises keep up with the market demand of the industry and take the large-scale and intelligent upgrading of equipment as the direction of high-quality development. Jiangsu Pengfei Group has successfully developed a large-scale pelletizing rotary kiln. Relying on the advantages of national enterprise technology center and rotary kiln special production and manufacturing, it has launched a series of pelletizing rotary kilns with an annual output of 600,000 to 6 million tons, breaking the monopoly of foreign technology "stuck in the neck" of domestic 10,000-ton rotary kilns, and driving the development of equipment manufacturing, new energy, new materials and other industries.

The large-scale pellet rotary kilnis a key equipment in the pig iron production process of the steel industry. The pellet rotary kiln is used to process the fine powder of the concentrate and process it into high-quality, high-strength, and more breathable pellet mineral products. Effectively improve the utilization rate of steel raw materials, reduce production costs, and have significant advantages in green environmental protection and social benefits.
