As a type of calcination equipment, the rotary furnace is mainly used for the primary rough processing of powder or mineral materials, and is suitable for thermal equipment for calcination, roasting, or drying of particles and powdery materials.
Simply understood, raw meal powder is fed into the kiln from the high end of the kiln's tail cylinder, and the cylinder has a certain slope. With the help of rotation, the raw meal is stirred and burned. Fuels such as coal powder and heavy oil are sprayed in from the lower furnace head end, which can be added Hot fuel, turning raw meal powder into clinker
The materials used in the rotary kiln cylinder are high-temperature and fire-resistant. With the rotation and friction of the rotary kiln, the materials are calcined from the tail machine, discharged at the head end, and the flue gas is discharged at the tail end When the raw material moves inside the drum, its particle movement may move upwards with the kiln in the raw material, or it may fall off the surface of the raw material. Only this process can make it move forward along the kiln length direction; Secondly, the movement of raw materials will also affect their heating conditions in the kiln, and the flipping of raw material particles will also affect the heating area of the raw materials
