Fuel Type: coal, gas, etc.
Kiln Type: rotary kiln & vertical kiln
Features: fully automatic, customizable, reasonable price
A caustic calcined magnesite kiln is a type of kiln used to produce caustic calcined magnesite (CCM), a highly reactive form of magnesium oxide (MgO). This process involves calcining magnesite ore at a relatively low temperature, typically above 1000°C, to achieve white solid magnesium oxide with a bulk density of less than 1 t/m³ for various industrial applications.
AGICO is a professional kiln solution supplier with more than 30 years of experience. We offer two production solutions for caustic calcined magnesite: the rotary kiln solution and the vertical kiln solution. In addition to caustic calcined magnesite kilns, our dead-burned magnesite kilns are also one of our best-selling products. Both solutions are designed to meet the varying needs of our customers, providing flexible and efficient options for magnesia production.

In addition to the kilns, we also provide auxiliary equipment needed for the production of caustic calcined magnesite, such as coolers, dust collectors, etc. If you are interested, please let us know your fuel type, output needs, production location, and other detailed information. We will promptly respond with the equipment configuration and a detailed quotation.
How To Select The Kiln?
Rotary kiln available:
Demand for high-activity caustic calcined magnesite (e.g., for the construction materials and chemical industries);
Large-scale and continuous production (annual capacity of 50,000 tons or more);
Raw materials are powdered ore or require a flexible adjustment of the calcination process.
Vertical kiln available:
Medium to small-scale production (annual capacity of 10,000 to 30,000 tons);
The raw material is lump magnesite ore (particle size 20~80mm);
Sensitive to investment costs, with lower requirements for product reactivity.
Why Choose To Invest In The Production Of Caustic Calcined Magnesite?
Abundant Availability Of Raw Materials: Magnesite ore is a widely distributed mineral resource found across the globe, with mining areas in Asia, Europe, Africa, the Americas, and Oceania. It is easy to extract and relatively inexpensive.
Low Production Costs: The technology for producing caustic calcined magnesite is well-established, with simple equipment and low energy consumption. This results in a lower investment threshold and more competitive operating costs.
Sustained Market Demand: The applications of caustic calcined magnesite are diverse and continue to expand. It is used in various industries, including flue gas desulfurization, wastewater treatment, cement production, animal feed production, fertilizer manufacturing, and soil improvement.
Profitability: By controlling the calcination temperature, it is possible to produce magnesium oxide with varying levels of reactivity, which can be used in high-value-added industries such as pharmaceuticals and electronic-grade materials. It increases profit margins by 30% to 50%.

Highlights Of AGICO Caustic Calcined Magnesite Kiln
High Efficiency & Energy Saving
High efficiency and energy saving are the key advantages of AGICO’s caustic calcined magnesite kilns. By optimizing the kiln design, improving the combustion system, and enhancing heat exchange efficiency, we achieve the efficient use of energy. For example, we employ staged combustion technology to more precisely control the flame temperature and length, thereby reducing heat loss. Additionally, the use of energy-saving refractory and insulation materials effectively reduces heat loss from the kiln body and minimizes energy consumption. Furthermore, we adopt advanced control systems to monitor and adjust parameters such as kiln temperature and gas flow in real time, which helps achieve precise energy control and reduce waste.
Environmental Protection & Pollution-Free
AGICO effectively reduces the emissions of harmful gases and particulate matter by adopting advanced combustion technologies and exhaust gas treatment equipment. We use low-nitrogen combustion technology and a Selective Catalytic Reduction system to reduce nitrogen oxide (NOx) emissions. The installation of high-efficiency dust collectors, such as bag filters, removes particulate matter from the flue gas. Processes like heat recovery, wet desulfurization, and denitrification effectively remove sulfur dioxide (SO₂) and nitrogen oxides (NOx) from the exhaust gases. Waste materials such as kiln ash and other solid waste can also be reused, for example, as raw materials for building materials or soil conditioners, promoting secondary utilization.
Stable Product Quality
AGICO’s high-temperature calcination technology for caustic calcined magnesite kilns ensures the full decomposition of magnesite, resulting in high-quality magnesium oxide products. By optimizing parameters such as the temperature distribution inside the kiln, gas flow rate, and material residence time, we ensure the uniformity and stability of the product during the calcination process. The kiln’s cooling system efficiently reduces the product temperature, preventing thermal expansion and structural changes, thereby ensuring the physical and chemical stability of the product.
