Dead Burned Magnesite

Dead Burned Magnesite Production Line Solution

The dead burned magnesite also called DBM, is a magnesium oxide product that is calcined at high temperature and has highly dense and solidified crystals. It is usually calcined at high temperatures of 1600-2200°C. Dead burned magnesite has excellent high-temperature resistance, corrosion resistance, and thermal shock stability. It is the key raw material to manufacture of kiln refractory bricks and monolithic refractory materials.

Strict Quality Control

Real-time online detection of calcination temperature and CO/O₂ content in the kiln. The finished products are tested for key indicators such as MgO content, SiO₂/CaO impurity control, bulk density, and hydration resistance.

Environmental Friendly

Dead burned magnesite solution is equipped with a baghouse dust collector and desulfurization system to effectively reduce the emission of dust and other hazardous substances. And equipped with a waste heat recovery system.

Strong Flexibility

The dead burned magnesite solution uses modular design, and customers can flexible configuration according to actual needs. The production capacity can also be adjusted according to market demand.

Dead Burned Magnesite Process

When high-quality magnesite arrives at the production line, it is stacked according to its grade, composition, etc. The large pieces of magnesite are then crushed into a jaw stone crusher or impact crusher for coarse crushing and broken into small pieces for subsequent processing. The coarsely crushed material will enter the cone stone crusher for fine crushing until it reaches the required particle size.

The crushed magnesite is first preheated using the waste heat from the kiln exhaust gas. Then it enters the calcination zone of limestone rotary kiln or vertical lime kiln, where it is usually calcined at a high temperature of 1600~2200℃. You can choose a limestone rotary kiln or vertical lime kiln according to your specific needs. The fuel used for calcination can be coal powder, natural gas, heavy oil, etc.

Magnesite calcined at high temperatures needs to be cooled quickly to prevent stress cracking and secondary oxidation. The temperature after cooling is usually below 100°C. Part of the heat can be recovered for secondary use. Dead burned magnesite is in block or granular form and can be ground using a limestone grinding mill.

Calcination requires the emission of a large amount of dust, so high-efficiency dust removal equipment must be equipped, such as a baghouse dust collector, industrial cyclone dust collector, esp electrostatic precipitator. These devices can not only capture dust but also recover valuable materials for secondary use. Ensure that the production process meets environmental protection requirements.

Dead Burned Magnesite VS Caustic Calcined Magnesite

Dead Burned Magnesite:

Dead burned magnesite has a higher firing temperature. The lattice structure is more complete and dense and has very low porosity.
Its chemical activity is extremely low, with almost no reaction with water, and not easy to react with acid, and has very good stability.
It can be made of magnesia bricks, magnesia carbon bricks, and other basic refractory materials.

Caustic Calcined Magnesite:

The crystal structure of caustic calcined magnesite is not fully developed as, a loose structure.
Certain defects and a large specific surface area are still retained in the crystal structure, so the chemical activity is high.
It can be the raw material of magnesium cement for the production of fireproof boards, lightweight partition boards, thermal insulation materials, and other building materials.

Dead Burnt Magnesite Uses

Dead burnt magnesite uses are extensive due to excellent high-temperature resistance, corrosion resistance, high chemical stability, and excellent thermal shock resistance.

Steel Industry: Dead burnt magnesite can be used as the lining of converters, electric arc furnaces, and ladles.

Lime Industry: Dead burnt magnesite can be made into refractory bricks for the lining of limestone rotary kiln.

Glass Industry: Refractory materials made of high-purity dead burnt magnesite are often used in the pool walls of glass melting furnaces.

Smelting Industry: In non-ferrous metal smelting furnaces, the furnace lining also needs to use dead burnt magnesite refractory materials.
