Introduction of Direct-Fired Rotary Kiln
Direct-fired rotary kiln can ensure good roasting quality, large production capacity of a single set of equipment, long service life, energy saving and environmental protection, and high mechanization and automation of supporting equipment. The rotary kiln has good versatility and can dehydrate, crush, screen, and pneumatically convey materials. Various combustion devices use different types of fuel to heat the rotary kiln, and the exhaust gas treatment system can recycle materials.
Working principle:
This kiln uses coal, coal gas, or natural gas as fuel. Flue gas generated acts as a direct heat source for roasting molybdenum concentrate, achieving optimal moisture content and high-quality molybdenum oxide output.
Performance & features:
Residual Sulfur Content: Meets industry standards for sulfur content, ensuring compliance with environmental regulations.
Fuel Consumption: The kiln consumes between 400 to 450 kg of coal per ton of molybdenum oxide produced.
Service Life: The expected service life of the equipment is 10 to 15 years, reducing the frequency of replacement and the associated costs.
Recovery Rate: Our kiln ensures a recovery rate of over 98%, optimizing resource utilization.
Advantages:
- High production capacity
- Energy-efficient and environmentally friendly
- Long operational lifespan
- High mechanization and automation

Direct-Fired Rotary Kiln Applications
The direct-fired rotary kiln is a versatile and highly efficient piece of equipment that is widely used in a range of industrial applications. Its ability to process a variety of materials at high temperatures and its flexibility in terms of fuel sources make it a critical component in many different sectors. Below are some key applications for the direct-fired rotary kiln:
1. Molybdenum Processing
One of the primary applications of the direct-fired rotary kiln is in the molybdenum concentrate roasting process. In this application, the rotary kiln is used to roast molybdenum concentrate to produce high-quality molybdenum oxide. The kiln's ability to provide a consistent heat source makes it ideal for ensuring that the material achieves optimal moisture content and high-quality output, which is critical for subsequent processing in industries such as steel production, electronics, and aerospace.
2. Lime Production
In lime production, rotary kilns are used to calcine limestone at high temperatures to produce quicklime (calcium oxide). This is a key material used in various industries such as water treatment, steelmaking, and construction. The direct-fired rotary kiln is ideal for this application because it provides an efficient heat source and ensures the proper chemical reactions required for the conversion of limestone to lime.
3. Aluminum Production
The direct-fired rotary kiln is also utilized in the aluminum industry, where it is used for the calcination of bauxite and other raw materials in the production of alumina (aluminum oxide). The rotary kiln's ability to handle high temperatures and provide a consistent heat source is essential for extracting aluminum from its ore. This process is critical for aluminum smelting, which is widely used in manufacturing industries, including aerospace, automotive, and packaging.
4. Iron Ore Processing
In iron ore processing, rotary kilns are used in the production of direct reduced iron (DRI). The direct-fired rotary kiln facilitates the reduction of iron ore using carbon, typically in the form of coal, to produce iron suitable for steelmaking. The high temperatures and controlled environment within the rotary kiln allow for efficient processing of iron ore, which is a vital step in the production of steel.
5. Red mud
The direct-fired rotary kiln is a valuable tool in the processing of red mud, offering benefits in terms of energy efficiency, environmental control, and the recovery of valuable metals and materials. As industries continue to seek sustainable solutions for managing waste products like red mud, the rotary kiln remains an essential piece of equipment, helping transform a potentially hazardous byproduct into useful materials that can be recycled or reused in other industries.
6. Carbon Black Production
In the carbon black industry, direct-fired rotary kilns are used to produce carbon black, a material derived from the partial combustion of hydrocarbons. Carbon black is widely used as a reinforcing agent in rubber products, as well as a pigment in inks, coatings, and plastics. The rotary kiln ensures consistent production and high-quality output by providing precise temperature control and efficient combustion.
7. Zinc Oxide Production
The rotary kiln is also used in the production of zinc oxide, a vital compound used in industries such as rubber manufacturing, electronics, and pharmaceuticals. Zinc oxide is produced by heating zinc concentrate or zinc ore in the presence of oxygen at high temperatures, where the rotary kiln provides the necessary heat and controlled environment for the process.
