Вращающаяся печь для обжига оксида цинка
Zinc oxide rotary kiln is one of the common methods for processing zinc-containing intermediate materials, and it is also a roasting equipment for calcining zinc. A zinc oxide rotary kiln is a kind of rotary kiln specially designed for the production of zinc oxide. Because zinc oxide is a fine powder, we must Make a set of specific rotary kilns for zinc oxide.

Outstanding features of zinc oxide rotary kiln
1. The equipment configuration of zinc oxide rotary kiln is simple, which reduces investment costs and improves productivity;
2. The zinc oxide rotary kiln has high efficiency, the zinc oxide obtained by calcination and smelting is of good quality, and the amount of nodules is small;
3. The entire zinc oxide production line runs smoothly and has a large production volume;
4. The entire production line has a small number of equipment, and each equipment and its capabilities ensure the rationality of the user’s investment.
Zinc oxide rotary kiln working principle
The working principle of zinc oxide rotary kiln is the whole process and principle of calcination of zinc and treatment of zinc-containing materials. Generally, zinc oxide rotary kiln is used to process zinc-containing filter cake. The zinc in the filter cake mainly exists in the form of zinc ferrite, oxides and sulfates.
Under the high temperature of the zinc oxide rotary kiln, the zinc ferrite reacts with solid carbon to reduce to metallic zinc, and the sulfates of zinc, lead and cadmium It was also reduced, and the well volatilized in the form of sulfide and gold.
The metal reduced and volatilized from the solid phase is re-oxidized under the action of the kiln atmosphere and is mainly produced in the form of oxides.
