ec@shyychina.comA zinc oxide rotary kiln is a type of rotating kiln designed for high-temperature calcination and thermal decomposition of zinc-bearing materials, such as zinc oxide powder, zinc ore, or zinc-leaching residue. The kiln consists of a rotating cylindrical shell lined with refractory materials, allowing raw materials to move gradually through controlled heating zones.
Compared with batch furnaces, the rotary kiln offers continuous production, uniform heat distribution, and stable product quality, making it an ideal calciner kiln for large-scale industrial applications.
Raw materials are fed into the kiln from the tail end. As the kiln rotates slowly and is installed at a slight inclination, the material moves forward under gravity and rotational force. High-temperature combustion gases generated at the kiln head provide the required heat for calcination.
The continuous rotation ensures uniform heating, enabling zinc compounds to undergo thermal decomposition and oxidation reactions, forming zinc oxide that is discharged at the kiln outlet.

A zinc oxide rotary kiln is mainly used for the calcination and thermal decomposition of zinc-bearing materials, such as zinc oxide powder, zinc ore, and zinc-leaching residue. And its primary function is to convert zinc-containing raw materials into stable, high-quality zinc oxide through continuous high-temperature processing.
Zinc oxide rotary kilns are suitable for medium to large-scale production. Typical industrial models can handle capacities ranging from approximately 180 tons per day to 10,000 tons per day, depending on kiln diameter, length, material properties, and operating conditions.
We offer fully customizable zinc oxide rotary kilns, with options for size, capacity, fuel type, and control systems. They can also integrate seamlessly with upstream equipment (like rotary dryers) and downstream systems (including cooling, conveying, and dust collection). This flexibility makes them an ideal solution for comprehensive EPC and turnkey projects.
Shanghai Yingyong Machinery Co., Ltd. is an experienced Chinese manufacturer specializing in rotary kiln systems, offering reliable equipment, international export experience, and EPC cooperation capabilities.
