The magnesium rotary kiln is a calcining rotary kiln produced by our company. As a core equipment used in the magnesite production lines, it is mainly used for calcination of magnesite and is widely used in metallurgy, chemical industry, building materials and other fields. Magnesite is an important basic raw material for the national economy. The magnesite rotary kiln system can produce sintered magnesia that meets the required performance.
Magnesium powder is mainly used as a reducing agent to make flash powder and lead alloys, and as a desulfurizer in metallurgy (when used as a raw material for desulfurizers in the metallurgical industry, the outside of the magnesium powder particles is wrapped with a layer of passivating agent to prevent the oxidation of the magnesium powder) , In addition, it is used in organic synthesis, lighting agents, etc.
Magnesite is a carbonate mineral of magnesium. Iron and manganese are often substituted for magnesium. However, the iron content of natural magnesite is generally not high. It is the main raw material for manufacturing alkaline magnesite refractory materials and extracting metallic magnesium. Magnesite The ore is mainly used for calcining refractory materials such as light-burned magnesia, sintered magnesia, and fused magnesia. At present, light-burned magnesite is mainly used in rotary kiln equipment.
advantages of magnesite rotary kiln
The principle of magnesite calcination method: Calcining magnesite at high temperature can produce magnesium oxide with low activity, and then through water digestion and filtration, basic magnesium carbonate or magnesium hydroxide can be obtained, which can be calcined at low temperature. Highly active magnesium oxide is obtained. Using magnesite as raw material, it is burnt at 600~800℃, hydrated at 80~200℃, filtered, purified, dried, ball milled, and then calcined at 450~600℃ to obtain active magnesium oxide with a high iodine absorption value of 140~200 mg/g.
- Drying, preheating, roasting and cooling during the calcining process of magnesite rotary kiln are carried out on the drying bed, roasting kiln, and cooling machine respectively. The operation process and process system are relatively easy to control, and the operation is simple and reliable.
- The magnesite rotary kiln can realize automatic temperature control and over-temperature alarm. It can adjust the temperature according to the amount of materials to achieve the desired calcination effect, making the production process faster and safer, and at the same time, it can also achieve secondary The waste heat of the inlet air is utilized, and the heat utilization rate is high.
- The magnesite rotary kiln has excellent kiln head and kiln tail sealing technology and devices, which can ensure that the equipment does not leak air or material, ensuring the reliability of the seal.
- The kiln head cover of the magnesite rotary kiln adopts a large volume method and a split kiln door structure to make the air flow more stable.

working principle of magnesite rotary kiln
The magnesite is fed into the rotary kiln through the kiln tail (high-end) chute. Due to the tilt and slow rotation of the cylinder, the magnesite rolls along the circumference and moves axially from the kiln tail (high end) to the kiln head (low end). Fuel from the kiln head through the burner into the kiln for combustion, heat by radiation, convection, conduction and other ways to the magnesite, magnesite in the kiln after preheating, decomposition, sintering and other processes, calcined into calcined white, and then discharged from the kiln head device.
