Large multi-purpose vertical roller mills are widely used for dry and wet grinding in mining, cement, and other industries. They can grind various materials efficiently with low energy consumption and noise. Vertical roller mills use advanced technologies and can grind materials continuously or intermittently, including non-metallic minerals and other hard, brittle materials to ultra-fine powder. Powder industries play an important strategic role in many national economies by accounting for half of industrial and agricultural output and materials used in high-tech, energy, environmental protection and developing western China. New highly efficient vibration mills are essential for processing ultrafine materials in industries like metallurgy, chemicals, and ceramics.
