Rotary Kiln for Lime Production¹

Product Description High capacity cement rotary kiln machine for saleApplication and operating principle:The rotary kiln is central equipment for cement clinkering system in the new large dry processing cement production, which can be used with unit-or-twin-stream preheater, calcining combustor. 90%-95% of the raw material which has been pre-calcined feeds into the slow rotating, inclining installed rotary kiln from the rear. Under the composite effect of circumferential tilting and axial movement, the material slowly flows through the whole drum, the fuel (coal dust, oil or natural gas) sprays from kiln head into high temperature zone for burning, which produces the required heat for physical and chemical reaction of combination and crystallization of material inside the kiln. Under the function of rear blower, the burning gas stream and material counter flow the whole kiln, completing heat exchange and physical/chemical reaction. The clinkered cement is discharge to the cooler. Characteristics:The kiln body is made of high-quality killed carbon steel or alloy steel plate and welded;The supporting type and rollers is of ZG35CrMo and 42CrMo steel;The sliding bearing is of non-scraping liner one with large clearance;The driving device adopts hard-toothed reducer, flexible sheet coupling, driven by DC motor;Hydraulic thrust roll is used;The kiln head and rear seal is of pneumatic or scaled type;With slow speed drive.Complete supply scope:It composed of kiln rear seal, supporting device, drum unit, driving unit, supporting device with thrust roll, hot kiln hood, hydraulic system for thrust roll(without refractory material) Electric control system can be supplied as customer's request.Technical parameter:ModelParameterMain MotorTrust Roller TypeSupporting TypeWeight tSpeed r/minInclination %Capacity t/dPower kWΦ3.2×500.674~3.373.51000160HydraulicSlide252.4Φ3.5×52.50.6~3.63.51500180366.5Φ4×560.35~3.53.52000250489Φ4×600.396~3.963.52500315523Φ4.3×640.4~3.963.53200420606.69Φ4.8×720.39~3.963.55000630853.3Φ4.8×740.35~445000630864Φ5.2×610.38~3.793.55500800859Φ5×80max3.546000800 Φ5.6×87max4.23480008001201Φ6×90max3.5410000845 ×2 Φ6×95max5410000950×2
