Raw Mill Blending Cement

Raw mill is mainly used for grinding raw materials in cement plant and is also suitable for grinding mineral ore and other materials in metallurgy chemical power plant it can work in open circuit or closed circuit with separator raw mill has features of various materials application continuous running big grinding rate easy control of product fineness
