The rotary kiln is mainly composed of the kiln shell, the transmission device, the supporting device, the retaining wheel device, the kiln head sealing device, the kiln tail sealing device, and the kiln headcover. There are close connections between the spare parts, so the quality of each spare part completely affects the operation of the entire rotary kiln production line.
The kiln shell is the main body of the rotary kiln. The shell of the kiln is made of steel plate. The thickness is typically in the range of 18-25 mm. According to the different bearing capacities of different parts, the thickness of the steel plate is also different. In order to ensure the quality of the shell, the rotary kiln shell is made of Q235-C steel plate, and the interior of it must also be inlaid with refractory materials.

There are three rotary kiln tires on the kiln shell, the purpose is to bear the weight of the revolving part and transfer the weight to the supporting device. Therefore, it is necessary to use high-quality cast steel materials, strictly guarantee the quality of the product, and ensure that the rotary kiln tire has sufficient strength, durability and rigidity.

A rotary kiln girth gear is fixed near the end of the kiln shell to transmit torque. The large gear ring is connected to the kiln shell through a tangential spring plate so that there is enough space for heat dissipation between the ring gear and the kiln shell. It can not only reduce the influence of the bending deformation of the kiln shell on the meshing accuracy, but also play a certain shock absorption and buffer effect, which is beneficial to prolong the life of the kiln lining. The large girth gear must drive the entire kiln cylinder to run for a long time, and its installation quality directly affects the smoothness of the rotary kiln transmission system, the stability of operation, the service life of the kiln lining and the operation rate of the rotary kiln. The quality requirements of the large gear ring are very high.

The supporting device is an important part of the rotary kiln. It bears the full weight of the kiln shell and plays a role in positioning the shell so that it can run safely and smoothly. The most important spare part of the supporting device is the supporting roller. The endurance quality of the supporting roller is relatively high, and it is also an index to measure the quality of the rotary kiln product. The supporting rollers processed by CHAENG have high tensile strength and good impact resistance, which guarantees the quality of the supporting rollers to a large extent.

Therefore, the quality of the key spare parts of the rotary kiln is very important, and the protection of the rotary kiln is irreplaceable, so it is inevitable to choose a good manufacturer. CHAENG has its own large-scale steel casting production base, with more than 500 high-precision equipments, and follows the national standard level 2 flaw detection standard to ensure the internal and external quality of the castings.
