Rotary kiln can be divided into cement rotary kiln, metallurgical rotary kiln, chemical rotary kiln, and lime rotary kiln according to different materials. Regardless of the type of kiln, the kiln shell is a key component of the equipment.
The rotary kiln shell is made of steel plate such as boiler plate and Q235C plate, requiring highly on dimensional accuracy and geometric tolerances.CHAENG adopts local forming method to design specific manufacturing process and welding method of single-segment cylinder according to the detailed requirements of the drawings. After the assembly and welding of the cylinder, perform the post-weld treatment, including non-destructive testing, post-weld heat treatment and pressure resistance test to ensure the high quality of kiln shell. Due to transportation reasons, the rotary kiln is composed of shell segments. Because the outer circle of the kiln cylinder is not processed, the perpendicularity of the end face to the center of rotation cannot be directly measured. In the process design, the perpendicularity of the end face is converted into parallelism and the coincidence of the axes at both ends according to the structure of the cylinder.

After years of development and experience, CHAENG has accumulated rich experience in casting, and has a large casting base in the north of Henan. Continuously introducing advanced casting equipment at home and abroad, and optimizing the process technology, CHAENG forms a systematic production process to ensure the quality of castings. Besides rotary kiln shell segments, CHAENG also launched a full range of spare parts services for rotary kiln and grinding mill, including rocker arm, grinding roller and grinding table for vertical roller mill; girth gear, support roller and riding ring for rotary kiln; girth gear and trunnion for ball mill, to provide customers with large mechanical spare parts needed in the whole kiln and mill, meeting the needs of different industries.
