1、 How to optimize the air duct design of magnesium oxide rotary kiln to ensure uniform heating?
1. Air duct layout. Design a reasonable air duct layout to ensure that air can be evenly distributed throughout the entire kiln. The distribution of air ducts should take into account the direction of material flow to ensure that the air can fully contact the material.
2. Burner position. The burner should be located in the appropriate position so that the flame can evenly cover the entire material layer. Adjust the angle of the burner according to the position of the material in the magnesium oxide rotary kiln to ensure that the flame can cover all materials.
3. Shape and size of the air duct. The shape and size of the air duct should be designed according to the size and material characteristics of the kiln to ensure optimal airflow distribution. The air duct should not be too narrow to avoid local overheating; It should not be too wide to avoid affecting the uniformity of the airflow.
4. Air volume adjustment. Design adjustable air doors or valves to control the airflow entering different parts of the kiln body. Adjust the air volume in real-time based on the temperature and material status inside the kiln to maintain an ideal calcination environment.
5. Thermocouples and sensors. Install thermocouples and temperature sensors at critical locations to monitor the temperature throughout the magnesium oxide rotary kiln. Use this data to adjust the airflow and burner settings to ensure uniform temperature.
6. Multi stage combustion. Multiple burners are installed at different positions in the kiln to achieve multi-stage combustion. Multi stage combustion can better control the temperature distribution of magnesium oxide rotary kilns, ensuring uniform heating of materials.
2、 How to ensure the uniformity of magnesium oxide products in magnesium oxide rotary kilns?
1. Raw material pretreatment. Fine crushing and screening of raw materials to ensure uniform particle size. Using uniform raw materials can reduce differences during the calcination process.

2. Design of feeding system. Design a uniform feeding system to ensure that materials can be evenly distributed inside the kiln. Use a screw conveyor or other uniform material distribution device to ensure that the material is evenly spread.
3. Kiln body rotation speed. Adjust the rotation speed of the magnesium oxide rotary kiln body appropriately to ensure that the materials can be fully mixed inside the kiln. By adjusting the speed, the residence time of materials in the kiln can be controlled to ensure sufficient calcination.
4. Arrangement of burners and air ducts. As mentioned earlier, arrange the burner and air duct reasonably to ensure even distribution of heat. Ensure that the flame can cover the entire material layer and reduce local overheating or underheating.
5. Cooling system design. Design an effective cooling system to ensure even cooling of the calcined material. The design of the cooling system can also affect the quality of the product.
