Product Description Product DescriptionThe production of secondary zinc oxide is a direct production process with a rotary kiln as the main equipment, which is called the rotary kiln volatilization method. The processing process is: mix the zinc oxide ore with coke powder or smokeless crushed coal in a certain proportion, and then put into the rotary kiln through the kiln tail discharge pipe. When the rotary kiln rotates, the materials slowly roll forward. Under forced blast, a high-temperature reaction zone of 1000-1200oC is formed in the kiln. Under this condition, the zinc metal compound in the charge contacts the reducing agent carbon, and is reduced by C and CO to metal zinc vapor and enters the gas phase. In the gas phase, it is oxidized by oxygen in the air to zinc oxide dust, which is captured by the dust collection system with the flue gas. The captured smoke dust is the low-grade zinc oxide product. In addition, metals enriched with zinc (such as lead, indium, etc.) are also reduced and oxidized into the product, while copper and precious metals gold and silver remain in the kiln slag.The main equipment of the process system includes: Roots blower, rotary kiln, kiln tail smoke chamber, surface air cooler, dust collector, desulfurization system, batching system, granulator, conveying equipment, etc.Product ParametersBasic ParametersProduct NameZinc Oxide Production LineDimensionΦ1.6x32m-Φ5.2×72mCapacity10,000-200,000 Tons/YearFuelCoke oven gas, natural gas, coal bed methane, pulverized coal, etc. Main Technical SpecificationsDimension/mSpeed(r/min)Slope/%Capacity(t/h)ReducerMotor ModelMotor Powerφ1.6×32m0.58-2.8542ZQ75-50YCT250-4A18.5φ1.6/1.9×36m0.53-1.5942.5-3ZQ110-7YCTZ50-4B22φ1.9×39m0.53-1.5943-3.4ZQ125-7YCT315-4A37φ2.2×45m0.214-1.643.54-5Main: ZS125-5YCT315-4B45Auxiliary:ZQ40-40Y112M-44φ2.5×50m0.62-1.53.55-6Main:ZS165-5YCT355-4A55Auxiliary:ZS50-1Y160M-67.5φ2.5×55m0.62-1.53.55-6Main: ZS165-5YCT355-4A55Auxiliary:ZS50-1Y160M-67.5φ2.8×55m0.62-1.53.56-7Main: ZS165-5YCT355-4B75Auxiliary:ZS50-1Y160L-611φ3.0×60m0.5-1.53.57-9Main:ZS165-3ZSN-280-11B125Auxiliary:ZS50-1Y160L-611φ3.2×64m0.4-1.53.58-10Main:ZS130-16ZSN-280-11B190Auxiliary:Zl50-1Y180L-422φ3.5×70m0.4-1.53.512-14Main:ZSY500-40ZSN-315-082280Auxiliary:Zl50-14Y180L-422φ4.0×80m0.4-1.53.516-20Main:ZLY630-35.5ZSN-315-12355Auxiliary:ZSY280-35.5Y200L-430Product Advantages Product Advantages High work efficiency: The cooler and kiln head cover adopt vertical design, which is small footprint, and has good sealing performance.Large production capacity, high degree of mechanization, and simple maintenance operations. Advanced performance: high operating rate, increased output by 30%, reduced heat consumption by 40%, and good production efficiency.Advanced structure: In addition to the main transmission, the transmission system is also equipped with an auxiliary transmission device that can still rotate the kiln body and prevent the kiln body from bending when the main power supply is interrupt.Main ProductsCompany ProfileShandong Bullis Metallurgical Engineering Co., Ltd. is a subsidiary of Heze Shuanglong Metallurgical Machinery Group and is located in Shandong Province, China.
