Superphosphate production

Course work in discipline "Constructional materials technology of inorganic substances" on " Superphosphate production" The physical and chemical bases of superphosphate production, presented the technological scheme of the process. These drawings technological scheme. The choice of construction materials processing equipment and the equipment. PRODUCTION OF SIMPLE SUPERPHOSPHATE, APATHY, GRANULAR PRODUCT. Weigher phosphoric flour is made of quality carbon steel Ст3, Ст4. Pressure tank of sulfuric acid produced from high-alloy cast iron (ferosylit) C15, ЧХ28 high chrome cast iron, which is lined with acid-resistant concrete, tile diabase, diabase putty. Pressurized water tank is made of corrosion-resistant steel 08Х17Т, 10Х14АГ15. Acid dispenser can be made of alloy steel 12Х18Н10Т, 08Х17Н5М3, gray cast iron СЧ18С17Т. The mixer is made of high-alloy steel 08Х17Н5М3, 10Х17Н13М2Т, ordinary quality steel Ст3, Ст4, who lined diabase tiles, diabase putty.
