Rotary kiln is main equipment for forging cement clinker.Rotary kiln is applied in chemical and metallurgy industry etc.Forging system of Rotary kiln is through technical renovations,use domestic and abroad advanced hydraulic stop wheel device and high precise pole pump, high precision adjustable speed valve,contact graphite sealing device etc. national advanced technologies.In order to increase automation degree, kiln head is used indurstrial TV monitor,analog fluorescent screen has been used for display of process flow;infrared scanning system has been adopted for forging zone to directly display the burning conditions in the computer.With the use of these new technologies,looks directly,convienent operation and reliable application.Therefore,increase equipment driving frequency.Comparing to the same specification, driving rate been increased 5-10% and heat consumption has been reduced 15%.
