Activated Carbon Rotary Kiln Lime Zinc Contenting Waste Material Kiln Furnace

The zinc-containing input materials are enriched in our rotary kiln using the so-called Waelz process to form Waelz oxide with a zinc content of at least 56 %. For this purpose, the input materials are introduced into the 40 m long rotary kiln together with other additives and handled at approx. 1,200°C.

Zhengzhou Hengyang Industry deploys the reliable rotary Kiln technology that successfully processes over 80% of the world’s recycled steel dust (EAF Dust). The rotary Kiln process is an established, energy-efficient and resilient technology used to treat zinc containing materials and residues.

End Uses of Zinc

Rotary Kiln Zinc Oxide is the main product of recycling EAF dust utilizing the Waelz Kiln technology. This product is sold to zinc smelters as an alternative to traditional zinc concentrates from mines. The zinc smelters produce pure zinc ingots or other high purity zinc products that are either sold to the steel industry for galvanization purposes or sold to other end-users for pigments, tires, chemicals or medicines.
