Detailed introduction
Introduction
Zinc oxide rotary kiln is the calcination equipment used for processing the zinc-bearing materials to get the zinc oxide. Because the zinc oxide is very fine powder, so we have to make a special rotary kiln for zinc oxide production, that is what we say now “zinc oxide rotary kiln”.
Features
The zinc oxide rotary kiln manufactured by ZK Corp. is specialized used and designed for the production of zinc oxide, as the zinc oxide exists in powdery.
1. Zinc oxide rotary kiln has simple configuration, it can reduce the investment costs and improve productivity
2. Zinc oxide rotary kiln has high beneficiation efficiency, and it can produce good quality zinc oxide by the calcination process, and this kiln has less nodulation.
3. The entire zinc oxide production line has smooth operation and large production capacity, in the smelting process, it can also greatly reduce the fuel cost.
Working Principle
Zinc oxide rotary kiln working principle is the whole process and principles of the calcined zinc, zinc-containing materials. Generally it adopts the zinc oxide rotary kiln to process of the zinc-containing filter cake. The zinc in the filter cake mainly exists in the form of zinc ferrite, oxide and sulfate. Under the high temperature in the rotary kiln, the zinc ferrite and solid carbon will produce the reaction for oxide-reduction, then it will get the zinc, at the same time lead and cadmium sulfate also be reduced, will volatilize in the form of sulfide and gold bucked out. The reduced and volatilized metal from the solid phase will be re-oxidation, and finally will be produced in the form of oxide.
