The Dolomite Magnesite Rotary Kiln is specialized high-temperature calcination equipment designed for the mining, metallurgy and refractory industries. As core equipment in the magnesia production line, it is mainly used for calcining magnesite ore, dolomite ore to produce high-quality active magnesia, light burned magnesia, dead burned magnesia and dolomite sand.
Our industrial magnesite calcination rotary kiln adopts advanced energy-saving technology and intelligent control system, ensuring high activity and purity of final magnesia products. It is the optimal choice for investors who plan to buy dolomite magnesite rotary kiln, build a new magnesia plant or upgrade traditional mining processing equipment.
Our dolomite magnesite rotary kiln features a robust inclined rotating cylinder, composite thermal insulation structure, and multi-stage labyrinth sealing device. This professional design minimizes heat loss and maximizes thermal efficiency, which is critical for cost-effective magnesite calcination.
Equipped with a precision burner and temperature monitoring system, the kiln accurately maintains the ideal calcination temperature (800°C - 1850°C) for producing different grades of magnesia. This makes our rotary kiln for magnesia highly versatile for both light-burned and dead-burned processes.
Crushed magnesite or dolomite ore is fed into the rotating cylinder of the dolomite magnesite rotary kiln. As the kiln rotates, the material moves slowly downhill due to gravity. During this movement, the ore is evenly heated by the counter-current hot flue gas.
The raw material undergoes dehydration, decomposition, and oxidation at high temperatures, completing the calcination process. The controlled residence time and temperature ensure the production of high-activity magnesia before being discharged and cooled. This is the standard process for a professional magnesia production line.
