This project aims to build an advanced grinding production line integrating automation, energy conservation, cleanliness, and stabilization. This project will precisely transform industrial solid waste, such as metallurgical slag, into highly active mineral admixtures. This will be used as a high-performance cementitious additive, achieving the dual benefits of solid waste resource utilization and low-carbon upgrading in the building materials industry. During the project preparation phase, the client systematically evaluated mainstream vertical grinding mills in the market, focusing on key indicators such as processing capacity, specific energy consumption, operational stability, and overall cost. After rigorous comparison, the client ultimately selected the Zenith Machinery LM vertical roller mill.
