Process Operation Instructions for Vertical Kiln System

Limestone (CaCO) is calcined at high temperatures (about 900-1100 ℃) in the kiln, decomposing into quicklime (CaO) and releasing carbon dioxide (CO ₂). Natural gas, as a fuel, is sprayed into the kiln through multiple burners evenly distributed around the circumference, providing the heat required for calcination and decomposition.…

"Zinc Slag Alchemy": How does the Secondary Zinc Oxide Rotary Kiln turn Waste into Treasure?

The crude zinc oxide rotary kiln is a core piece of equipment for processing zinc-containing materials through high-temperature calcination. Its principle is based on the physical and chemical properties of zinc compounds. Within the kiln, at temperatures of 1100-1250°C, the zinc in zinc-containing slag (such as steelmaking dust and lead-zinc slag) reacts with a reducing agent (such as coke) to produce crude zinc oxide and gaseous products.…

Green Transformation Engine: Coal Gangue Suspension Calcination Decarbonization Technology Boosts Circular Economy

The suspension calcination decarbonization method significantly reduces the carbon content in coal gangue. If carbon remains in coal gangue, it slowly oxidizes in the natural environment, releasing not only the greenhouse gas carbon dioxide (CO₂) but also harmful gases such as carbon monoxide (CO) due to incomplete oxidation. Through suspension calcination, most carbon is collected and processed in the form of CO₂, effectively reducing the escape of harmful gases into the atmosphere.…
