production of zinc sulfate

1 Appearance traits: Zinc sulphate is divided into two types: ZnSO4.7H2O and ZnSO4.H2O, white or slightly brownish yellow granules, crystal or powdery, and easily soluble in water.
2. Product use: It is mainly used as raw materials for the manufacture of zinc antimony and other zinc salts, important auxiliary materials such as viscose fiber and nylon fiber, agricultural compound fertilizer, printing and dyeing mordant, wood and leather preservation agent, bone glue clarification and preservative , medical emetics and fungicides, food, electroplating, mineral processing, prevention of fruit tree disease, circulating cooling water treatment.
3. Production of main raw materials: zinc ash or zinc oxide, sulfuric acid and other suitable raw materials.
4, the main process of production: measurement "chemical" purification" refined" steamed "crystal" separation "package.
5. Main equipment for production: water tank, compounder, purifier, refiner, steamer, crystallizer, anti-corrosion pump, high-efficiency cyclone, separator, centrifuge, fan, etc. ZnSO4.H2O requires a fluid state dryer.
6, product quality: ZnSO4.7H2O content% 92-97, ≥92% is a qualified product. ZnSO4.H2O content% 95-98, ≥95% is a good product.
7.      select     ion of production equipment: common type, first type, high type.
8. Environmental protection: According to the configuration of process equipment, wastewater and waste gas can be treated.
9. Investment situation: According to the advanced level of impurity components and equipment such as product output and raw material content.
