Rotary kiln is the main equipment for sintering cement clinker. The rotary kilns was sold by our company ,which can be used for chemical industry, metallurgy industry and etc. Through technical renovations, the rotary kiln sintering system equipment made by our company has adopted high measuring precession plunger pump, variable speed adjusted valve, contact graphite block air seal and other national advanced technologies. In order to raise up automation degree, industrial TV has been used at the kiln head for monitoring of kiln, analog fluorescent screen has been used for display of process flow, infrared scanning system has been adopted for sintering zone to directly reflect the burning conditions on the computer. With the use of these new technologies, it is directly in vision, convenient in operation and reliable in use. Therefore, the operation rate can be raised. Compared to been raised 3-5% up, production has been increased 5-10% and heat consumption has been reduced 15% down.
