Recently, the 450,000-ton-per-annum slag ultrafine powder production line—constructed by Xinxiang Great Wall for a client in Hebei—was officially completed and has commenced operations.

　　Utilizing blast furnace slag from Xinggang as its raw material, this project represents a strategic move by the Hebei client to extend their special steel industry value chain downstream. By "turning waste into treasure," they are producing slag ultrafine powder—a fundamental material for the construction industry.

　　Based on the client's requirements, Xinxiang Great Wall selected the GRMS40 vertical roller mill as the primary grinding equipment for this project. The entire project features a scientifically sound design and reliable equipment, ensuring high production efficiency while simultaneously prioritizing environmental protection and helping the client save on investment costs.
