Zinc oxide rotary kilns are primarily used for the reduction roasting of zinc-containing waste. Suitable materials include zinc concentrate, zinc-containing sludge, zinc-containing tailings, steel mill dust, steel mill flue dust, zinc-containing flue dust, zinc-containing dust sludge, blast furnace secondary ash, converter secondary ash, electric furnace dust, steelmaking LT ash, converter OG sludge, blast furnace gas sludge, and blast furnace gravity ash. Production lines can be designed to process 0.5 to 1500 tons of raw materials per day, depending on needs.
Applications
Suitable for the rubber, coatings, chemical, glass, and electronics industries.
Product Introduction
The zinc oxide rotary kiln is primarily used for the reduction roasting of zinc-containing waste. Suitable materials include zinc concentrate, zinc-containing sludge, zinc-containing tailings, steel mill dust, steel mill flue dust, zinc-containing flue dust, zinc-containing dust sludge, blast furnace secondary dust, converter secondary dust, electric furnace dust, steelmaking LT dust, converter OG mud, blast furnace gas mud, and blast furnace gravity ash. Production lines can be designed to process 0.5 to 1500 tons of raw materials per day, depending on needs.
Key Advantages
● The zinc oxide rotary kiln offers simple equipment configuration, reducing investment costs and improving productivity.
● The zinc oxide rotary kiln boasts high efficiency, producing high-quality zinc oxide with minimal nodules through calcination and smelting.
● The entire zinc oxide production line operates smoothly and achieves high throughput.
● The entire production line utilizes a small number of equipment units, each optimized for its intended purpose, ensuring a reasonable investment.
Operating Principle
The material entering the kiln rotates continuously as it moves toward the kiln head. The combustion of coke powder in the material releases heat, reducing the zinc in the material to zinc vapor at a certain temperature. Upon encountering oxygen, the zinc undergoes an oxidation reaction, converting it to zinc oxide, which enters the flue gas treatment system along with the flue gas. Once the burner is ignited, the material continues to burn, and the Roots blower only needs to continuously replenish air.
