The rotary kiln is a cylindrical substance with a certain inclination, the inclination is between 3 and 3.5%, the rotation of rotary kiln means to the stirring of materials in rotary kiln, so that material are mixed with each other, the contact promotes reaction. The combustion of kiln head generates a lot of heat, heat flame radiation, heat convection, brick kiln (kiln leather) conduction to the material. The materials rely on the slope of kiln shell and the rotation of the kiln move forward in the kiln.
The working principle of rotary kiln: rotary kiln is the host device of cement production.
The raw material from the of kiln inlet cylinder at elevated temperature enter the cylinder body. Due to the inclination of Kiln rotary and slow rotation, so that the materials produce composition motion along the circumferential direction and the axial from high-end to low-end. Through the decomposition of the raw material in the kiln, firing and cooling process after firing the cement clinker from the low-end of the kiln shell unloaded out into the cooler.
Through the decomposition of the raw material in the kiln, after firing and cooling process, firing the cement clinker from the low-end of the kiln shell and they are unloaded out, then enter the cooler. Fuel from the kiln sprayed into the device, and the combustion is performed in the kiln, the amount of heat emitted heats the raw material, when the raw material makes hot exchange with other materials, and then generate hot air, the materials from the kiln feed end enter the kiln inlet system,Finally, they are discharged out the atmosphere from the chimney.
The structural characteristics: rotary kiln is mainly composed of the kiln shell, the drive means, the support means, the means of the gear wheel, kiln head sealing means, kiln sealing means, the kiln hood.
