The Russian Metallurgical Plant Severstal took an important step in its environmental and production strategy, starting the installation of the largest ball -grinding balls in the world on its new complex for the production of iron ore pellets in Cherepovets. The complex designed for annual processing of 10 million tons of pellets will replace the old sintering technology with more efficient and environmentally friendly methods.
project progress and key components
Three ball mills - each with a diameter of 6.7 meters and A length of more than 13 meters - are the largest in their kind around the world. These massive machines are designed for drying and dry grinding of iron ore using small balls. Along with ball mills, construction crews install another basic technological equipment, including firing machines, granulators and vertical mills. More than 30 percent of metal structures have already been installed. Auxiliary infrastructure, such as galleries and conveyors of the presentation of raw materials, is also under construction, while modernization efforts are continuing to improve the flow of raw materials.
“Installation of three ball mills is the most important and complex operation today. Despite the calls of the industry, we are still committed to key environmental projects and a decrease in environmental impact, ”said Alexander Shevelev, general director of PJSC Severstal, emphasizing the significance of this milestone. sintering
