Due to the special use environment, Raymond mill must be properly treated before and during use. In the selection of materials in the design stage of Raymond mill, the media environment should be considered, and the materials must have good adaptability, corrosion resistance and thermal insulation. In the design of the Raymond mill structure, the welding seam should be minimized to prevent corrosion after penetration. At the production stage of Raymond Mill, we must also pay attention to anti-corrosion work. The mechanical materials should be inspected and registered. We must pay full attention to the anti-corrosion work of Raymond Mill, especially to strictly control the design specifications and design quality. When the Raymond mill is damaged, by repairing or replacing the parts, the Raymond mill can be guaranteed to work normally, that is, under low-cost maintenance, economic efficiency is improved. Then, the necessary maintenance work on the Raymond mill can keep it in good operating condition and prolong the service life of the Raymond mill.
