Vertical Mills

CITIC vertical roller mills are engineered for cement, slag and raw material grinding. The modular design with 2-4 rollers provides flexible configuration for different material hardness and capacity requirements. The integrated dynamic classifier enables precise fineness control. Anranst supplies grinding rollers, table liners and classifier vanes in Cr26 high-chrome iron for Chinese cement and steel plants.
