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 dry process 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, convienent in operation and reliable in use. Therefore, the rmalcondition can be raised. Compared to been raised 3-5% up, production has been increased 5-10% and heat consumption has been reduced 15% down.Technical Data of Dry Process Rotary KilnSpecificationmφ4.3×64φ4.8×74φ5.0×74φ5.6×87φ6.0×95Capacityton/day350050006000800010000Slope of the kiln shell %44444No.of supporters33333Type of thrust rollerHydraulicHydraulicHydraulicHydraulicHydraulicRotating speed of kilnMain driving r/min0.4-4.00.35-40.35-4Max 4.23Max 5Auxiliary driving r/min7.938.527.588.79.2Main drivingElectrica MotorModelZSN4-355-12ZSN4-400-092ZSN4-450-092ZSN4-450-12ZSN4-500-092Rated power kw400630710800950×2Speed regulation range r/min100-1000150087.5 1000100 1000100 1000Rated voltage V440660600600600ReducerModelYNS1400-31.5VIBLJH710C-SW305-40JH880C-28JH900C-SW305-25JH900C-SW305-28Total ratio31.542.22626.81223.90126.646Auxiliary drivingElectrica MotorModelY200L-4Y250M-4Y250M-4Y280M-4Y315M1-4Rated power kw30555590132Rated speed r/min14701480148014801490Rated voltageV380380380380380 ReducerModelYNS497-45ZCJH220C-SW302-28JH280C-45ZSY400-35.5- 1ZSY450-35.5- 1 Total ratio45284535.79535.795 Total weight excluding refactory brick (ton)Weight of discharging kiln hood (ton)550.536854458944812011580
