Dolomite Rotary Kiln
The dolomite rotary kiln has an optimized structure and intelligent control. While ensuring the quality of finished products, energy consumption and operating costs are greatly reduced.
Dolomite Rotary Kiln Soution
Dolomite rotary kiln is a professional equipment for the calcination of dolomite (calcium magnesium carbonate). It is one of the important equipment in a dolomite calcination plant. The dolomite rotary kiln is different from the limestone rotary kiln. Dolomite calcination requires more precise temperature control. Dolomite rotary kiln has the advantages of stable product quality, large-scale continuous production, and high thermal efficiency. It is the first choice for calcination of dolomite.

Advantages of Dolomite Rotary Kiln
Good quality of products
The dolomite rotary kiln can precisely control calcination temperature and time. Ensure the dolomite is fully decomposed, with no over-burning or under-burning. Finally, we have the finished dolomite with high chemical activity.
High efficiency
The dolomite rotary kiln features a long barrel and large volume, enabling uninterrupted 7×24-hour operation. It is suitable for large-scale industrial production. It is a high degree of automation, stable operation, and small errors.
Good economic benefits
A dolomite rotary kiln usually has a vertical preheater. The high-temperature exhaust gas from the kiln tail is used to preheat the raw materials and reduce fuel consumption. And it can use multiple fuels, thereby reducing operating costs.
Environmentally friendly
The dolomite rotary kiln uses advanced sealing technology to prevent air leakage. It is equipped with a baghouse dust collector and other dust removal equipment. Flue gas emissions meet strict environmental protection standards.
Energy-saving and Environmentally Friendly Technologies
—— The design of the dolomite rotary kiln puts energy conservation and environmental protection first. Our dolomite rotary kiln has multiple advanced technologies, ensuring high output while achieving green production.
Preheating system
- The dolomite rotary kiln has a vertical preheater. It uses the high-temperature exhaust gas generated during the calcination process to preheat the dolomite. The temperature of the raw materials can reach 800℃ or even higher before entering the calcination zone. This design can reduce fuel consumption. At the same time, improve overall production capacity.
Waste heat recovery
- The dolomite rotary kiln has a cooling system. The calcined dolomite is cooled to a suitable temperature in the cooling system for easy storage and transportation. The cooled hot air is collected and reused. Energy is fully utilized, and energy waste is reduced.
- The dolomite rotary kiln is equipped with a baghouse dust collector at the end of the kiln. It can capture dust particles and ensure that the emission concentration is lower than the national standard. Combined with the sealing of the kiln head and kiln tail, it can more effectively prevent the random emission of dust. The flue gas dust emission concentration can be stably lower than 10mg/Nm³.
Reasonable Dolomite Rotary Kiln Design
- Kiln design
The kiln body is made of high-quality high-strength steel using advanced welding technology. We have determined the optimal aspect ratio of the kiln tube through scientific calculations. Ensure that dolomite is fully and evenly calcined in the cylinder. Avoid over-burning or under-burning.
- Sealing of kiln head and kiln tail
The seals at the kiln head and kiln tail are all sealed with advanced sealing technology. Prevent smoke from escaping from the kiln. It minimizes heat loss and increases thermal efficiency by 5%-10%. It also prevents the random emission of dust and pollution of the environment.
- Refractory lining
According to the temperature and chemical environment of different sections, kiln refractory bricks of different materials and grades are scientifically selected. Effectively reduce temperature loss and extend the service life of the dolomite rotary kiln.
Core Application Areas
Metallurgical Industry
Heavy-burned dolomite is an important material for manufacturing refractory materials, such as dolomite bricks and magnesia-calcium bricks. The structure of dolomite is dense and stable; it has high fire resistance and corrosion resistance. It is used for steelmaking furnace lining, lime calcination kiln lining, etc.
Steelmaking desulfurization
Lightly burned dolomite is an important desulfurizer during steelmaking. It reacts with harmful elements in molten iron to form slag. Thereby purifying molten steel and improving steel quality.
Environmental protection industry
Lightly burned dolomite is an excellent neutralizer for acidic substances. It can effectively remove sulfur dioxide from industrial flue gas. Neutralization of acidic wastewater. Improve acidic soil and promote crop growth.
Dolomite Calcination Plant Project
If you need to build a dolomite calcination plant, we can also do that. We promise to provide you with customized dolomite calcination plant solutions with the fastest speed and the most professional management.
Finished product of dolomite rotary kiln:
1. Lightly burned dolomite: Lightly burned dolomite is also called activated dolomite. It is calcined at relatively low temperatures. It has a loose structure and a large specific surface area. It has a very high reaction rate when reacting with other substances and needs to be stored in a sealed container. It is commonly used in steelmaking, flue gas desulfurization, wastewater treatment, and soil improvement.
2. Heavy-burned dolomite: Dead-burned dolomite is also called sintered dolomite. It is calcined at a higher temperature. It has high structural density, low activity, and high temperature resistance. It is not easy to react with water and can be stored in the atmosphere with stable performance. It is often used to make refractory materials.
