The Raymond mill is a versatile grinding equipment optimized for industrial fine powder production. It has clear material adaptation standards, suitable for grinding non-flammable, non-explosive minerals, chemical products and building materials that feature Mohs hardness less than 6 and humidity below 6%. The equipment realizes stepless adjustment of finished product particle size in the range of 40 to 400 meshes, enabling flexible switching of different fineness production. It covers the processing of most common soft and medium-hard materials such as barite, calcite, potash feldspar, limestone, talc, dolomite and gypsum, with strong practicality in actual production.
