Product Description Manufacturer Zinc Oxide Rotary Kiln Used in Coating, Mining, Chemical Industry Product DescriptionZTIC  Zinc oxide rotary kiln technical characteristics:1. Kiln body is made of high quality composed of carbon steel or alloy steel plate and automatic welding;2 .Tyre,Support Roller,Open gear adopts alloy cast steel;3 .Sliding bearing with large gap not scraping tile bearing;                 4.Transmission device adopts hard tooth surface reducer, flexible diaphragm coupling, dc motor;5. Adopts hydraulic gear wheel;6. Preheater scales were used respectively to veiw of kiln head, and cylinder pressure tight seal;     7 . A slow drive device.Zinc Oxide Rotary KilnZinc oxide is used in rubber industry, mainly used for natural rubber, latex and rubber active agent compound using. Secondly it is used as intensifier and coloring agent. It is widely used in coatings, printing ink, paper making, medicine, chemical industry, ceramic, and glass, match, cable and cosmetics industries.Features and usages of zinc oxide rotary kiln1,Making the rubber more abrasion resistance,tear resistance ,more flexible;2,Reducing the cost of production,stable curing performance;3,Production can be widely used in paint,ink,Qibu shading,printing the dye;4,As the raw materials of rubber adhesive plaster in the pharmaceutical industry,also used to paint.Smelting process of zinc oxide by rotary kilnRotary kiln is the zinc ore raw material and coke coal powder and lime crushed into particles less than 40 mesh, zinc ore raw material and coke coal and lime according to 1∶ (0.40 ~ 0.5) : Then the mixture is made into particle mixture with an effective diameter of 8-15mm. Finally, the particle mixture is put into the rotary kiln. The ingredients are continuously transferred to the drying and preheating section (about 11m,650-700 degrees), then to the intermediate temperature section (about 17m,700-850 degrees) and finally to the high temperature section (about 17m,850-1100 degrees,907 degrees is the boiling point of Zn) for smelting. Under high temperature into zinc vapor, and then into the hot air for oxidation, the production of zinc oxide after cooling, cyclone separation, with a cloth bag to capture fine particles, so get zinc oxide is called "indirect zinc oxide".When smelting zinc oxide ore containing 20% ~ 25% zinc or industrial slag containing zinc in rotary kiln, it can greatly save coke or coal. The smelting product has the characteristics of good quality, improved productivity and small nodulation.Using rotary kiln calcination process, when smelting zinc oxide ore with zinc content of 20% ~ 25%, the yield rate is 15% ~ 20%. (Namely 5-6T raw ore out of 1T zinc concentrate)Process of zinc oxide rotary kilnFirst, crushing and millingThe dry crude material will be crushed and milled first.Second,calcinationAfter milling, the materials would enter the kiln outlet( high end of the cylinder) through the preheater, and then are fed into the kiln by the tremie pipe. Meanwhile, The heating source is sprayed into kiln by burner barrel in the head of the kiln. Due to the inclination of the cylinder and slow rotation of the cylinder, the materials roll in hoop direction. During this process, They will be calicinated, reacted, decomposed in succession through the calcinating section, reaction section, decomposition section,Third,coolingThen the materials are discharged from the head of the kiln and enter the cooling device and be cooled.At last, screeningThen they will go through the screens and final products will be conveyed to the yard. The big size materials will be sent back and processed. Parameters of  Zinc oxide rotary kiln NOModel(m)Drawing       No.basic parameterMain ReducerMain MotorCatch wheel typeSupport bearingWeight   (t)Speed r/minIncline   %Capacity   t/dModelPowerkWSpeedr/min1Φ3.45×52J9680.35 ~0.85350Worm gear reducer A=450,i=1275 hydraulicrolling412.52Φ4×58J9780.35 ~3.55400 250 hydraulicsliding3413Φ4.15×58.2J9750.35 ~0.75756 55 ×2 hydraulicsliding637 Note: Parameters should refer to the specific contract.    Company Profile FAQQ: Why we believe in luoyang zhongtai industries co., ltd:A: 1.
