Zinc oxide rotary kiln is a device for calcining zinc-containing intermediate materials. Zinc oxide rotary kiln is widely used in the production of zinc oxide with advanced structural properties.
Zinc oxide is a commonly used chemicaladditive widely used in the production of plastics, silicate products,synthetic rubber, lubricants, paints, ointments, adhesives, foods, batteries,flame retardants and other products. Zinc oxide rotary kiln is a device for calcining zinc-containing intermediate materials. Zinc oxide rotary kiln is widely used in the production of zinc oxide with advanced structural properties. Below is the engineer of ZK CORP to introduce the zinc oxide rotarykiln.
Working principle of zinc oxide rotary kiln
The working principle of zinc oxide rotarykiln is the whole process and principle of calcining zinc and treating zinc.Zinc oxide rotary kilns are generally used to treat filter cakes containingzinc. The zinc in the filter cake is mainly in the form of zinc ferrite, oxidesand sulfates. At the high temperature of the zinc oxide rotary kiln, zincferrite and solid carbon act to reduce to metal zinc, while zinc, lead, and cadmiumsulfate are also reduced and volatilized in the form of sulfides and gold.Metals that have been reduced and evaporated from the solid phase arere-oxidized under the effect of the kiln atmosphere and finally produced in theform of oxides.
Process flow of zinc oxide rotary kiln
1. The zinc charge and coking coal arecrushed into particles smaller than 40 meshes, and the zinc charge and thecoking coal are mixed in a ratio of 1:0.30-0.35 to obtain a mixture.
2. The mixture is made into a granular mixturewith an effective diameter of 8-15 mm, and finally the granular mixture is putinto a zinc oxide rotary kiln for smelting.
3. When zinc-bauxite or zinc-containingindustrial slag with a zinc content of 15% to 25% is used for smeltingzinc-bauxite production, significant coking or coal burning can be achieved.
4. High productivity and good quality of zincoxide obtained through smelting.
The zinc oxide rotary kiln produced by HenanZhengzhou Mining Co., Ltd. has the following characteristics:
1. Simple equipment configuration, lowerinvestment costs and higher productivity.
2. High beneficiation efficiency, the qualityof zinc oxide obtained by calcinations smelting is good, and the amount ofnodulation is small
3. The whole zinc oxide production line runssmoothly and has a large production volume. During the smelting process, thefuel cost is also greatly reduced.
