1. Cement industry
Clinker production: The rotary kiln is the core equipment of cement production. It is used to calcine raw materials such as limestone and clay at a high temperature of about 1450℃ to produce cement clinker (the main component is calcium silicate).
Process steps: drying, preheating, decomposition (carbonate decomposition), sintering and cooling.
2. Metallurgical industry
Alumina production: Calcination of aluminum hydroxide (Al(OH)₃) to produce alumina (Al₂O₃), which is used for electrolytic aluminum.
Iron ore treatment Magnetization roasting: Convert weakly magnetic hematite (Fe₂O₃) into strongly magnetic magnetite (Fe₃O₄) for magnetic separation.
Direct reduced iron (DRI): Use coal or natural gas to reduce iron ore to produce sponge iron (used for electric arc furnace steelmaking).
Other metals:
Roasting molybdenum concentrate, zinc ore, lead ore, etc., desulfurization or oxidation.
Ilmenite (FeTiO₃) is calcined to produce artificial rutile (TiO₂).
3. Chemical industry
Activated carbon production: Carbon-containing materials (such as coconut shells, coal) are made into porous structures through high-temperature activation (800–1000°C).
Catalyst preparation: Calcination of catalyst carriers (such as alumina, molecular sieves) to enhance activity.
Carbonate decomposition: Calcination of chemical raw materials such as barium carbonate and strontium carbonate.
Petroleum coke calcination: Remove volatiles, increase carbon content, and use it as an anode for aluminum electrolysis.
4. Environmental protection and waste treatment
Hazardous waste incineration: Treatment of medical waste, organic solvents, oily sludge, etc., high temperature (above 1200°C) to decompose toxic substances (such as dioxins).
Contaminated soil remediation: Pyrolysis of pollutants such as petroleum hydrocarbons and pesticides in the soil.
Municipal waste incineration: Some processes are used for incineration power generation or resource processing.
5. Building materials and refractory materials
Lime production: calcining limestone (CaCO₃) to produce quicklime (CaO), which is used in the steel, construction and other industries.
Ceramic aggregate preparation: expanded clay, shale, etc. are made into lightweight aggregates for concrete.
Refractory material calcination: such as calcining high-alumina bauxite, magnesia, etc.
6. Other applications
Mineral processing: calcination and modification of bentonite and kaolin to improve adsorption or whiteness.
Pigment production: calcination and surface treatment of titanium dioxide (TiO₂).
Nuclear waste solidification: high-temperature solidification of radioactive waste.
Advantages of rotary kiln
Strong adaptability: can process various forms of materials such as blocks, powders, and slurries.
High temperature stability: high temperature resistance (up to 1600℃), suitable for complex chemical reactions.
Continuous production: high degree of automation and large processing capacity.
Environmentally friendly and controllable: equipped with waste heat recovery and exhaust gas purification systems to reduce energy consumption and pollution.
