Looking for a reliable rotary kiln supplier?
Yes, We provide a one-stop solution for rotary kilns worldwide!
Rotary kiln is the core calcination equipment widely used in cement, active lime, metallurgy, chemical industry, mineral processing and solid waste disposal industries. As the key equipment of the complete production line, it is mainly applied for high-temperature calcination, sintering and drying of various bulk and granular raw materials.
Our industrial rotary kiln adopts advanced structural design, high-quality refractory materials and high-temperature resistant steel components, featuring high thermal efficiency, low energy consumption, stable operation, large processing capacity and long service life. Equipped with reliable transmission system, sealed structure and intelligent temperature control system, the whole kiln body runs smoothly and reduces dust emission to meet international environmental protection standards.
The cylinder of the rotary kiln is made of rolled steel plates, and is lined with refractory lining at a specified slope with the horizontal line. It is supported by three wheels on each gear support device. A large gear ring is fixed on the cross inner cylinder near the feeding end wheel with a tangential spring plate, and a small gear mesh with it. During normal operation, the main drive motor transmits power through the main reducer to the open gear device, driving the rotary kiln. The material enters the rotary kiln for calcination from the kiln tail (at the high end of the cylinder). Due to the tilting and slow rotation of the cylinder, the material not only rolls in the circumferential direction but also moves axially (from the high end to the low end), continuing to complete its process. Finally, the generated clinker enters the cooling machine through the kiln head cover for cooling. The fuel is sprayed into the kiln from the kiln head, and the waste gas generated by combustion is exchanged with the materials before being exported from the kiln tail.
