Waelz kiln is a the equipment of recovering zinc and other relatively low boiling point metals from metallurgical waste (typically EAF flue dust) and other recycled materials.

Our Advantage

    Waelz kiln is a the equipment of recovering zinc and other relatively low boiling point metals from metallurgical waste (typically EAF flue dust) and other recycled materials.
     
    Waelz kiln manufactured by ZK Corp. is specialized used and designed for the production of zinc oxide, as the zinc oxide exists in powdery. Because the zinc oxide is very fine powder, so we have to make a special rotary kiln for zinc oxide production.
     
    Working principle:
     
    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.
