Rotary kiln is the main equipment for sintering cement clinker. The rotary kilns produced by our company can be divided into dry process and wet process. They can also be used for chemical industry, metallurgy industry and etc. Through technical renovations, the rotary kiln sintering system equipment made by our company has adopted h9igh 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 ate 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 direct in vision, convenient in operation and reliable in use. Therefore, thermal condition can be stabilized and running rate of equipment can be raised. Compared to same sized equipment, its running rate has been raised 3~5%up, production has been increased 5~10% and heat consumption has been reduced 15% down.
