    Rotary kiln has more than hundred years of history, both at home and abroad have high visibility.In recent years due to the rising power of science and technology, on a global scale rotary kiln of the new technology emerge in endlessly, and according to the different characteristics of the material, the different types of rotary kiln out one after another, energy conservation and environmental protection kiln is one of them.

    Performance and features of clinker rotary kiln

    1. With advanced structure, the low pressure loss of the vertical preheater can speed up the preheating process, the decomposition rate in the kiln of the preheated limestone can be 20-25%, and can use directly the 10-15mm fine grade limestone.

    2.Both ends of rotary kiln is sealed by combination scale, which ensures the index of air leakage less than 10%. In order to lessen the radiation loss, it adopts compound refractory materials

    3.Round or square vertical cooler with filling type and ventilated area, which make the lime temperature 800 degree celsius + ambient temperature. It is easy to transport, store, and can be preheated the secondary kiln air to above 700 degree celsius , which reduce the moving parts and special materials.

    Structure of cement rotary kiln

    Rotary kiln is made up from barrel, gearing, splints, block wheel support device, kiln head, sealing kiln tail, kiln hoods and combustion device, etc. The rotary is the rotary part to be heated; it is welded from high-quality still steel plate. The rotary is supported by the 2 ~ 7 gears sliding bearing through tyre. And then machine or hydro-damper was set up on the bearing device to control the bearing. The gearing make the rotary swing at the required speed by the geared ring in the middle of the rotary. Due to the need of installation and maintenance, larger kiln has auxiliary drive device to make the rotary at low speed; To prevent cold air entering into the dust or smoke spill from the rotary, sealing devices were set up on the feeding end and discharge end in the rotary.
