Cement production line use rotary kiln

タイトルまたは説明

Application and operating principle:
The rotary kiln is central equipment for cement clinkering system in the large dry processing cement production, which can be used with uni-or twin-stream preheater, calcining combustor *0%**5% 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, dustm oil or natural gas) sprays from kiln head into high temperature zone for burning, which produces the required heat for physical and chemical reactionof combination and crystallization of material inside the kiln. Under the function of real blower, the burning gas stream and matreial counter flow the whole kiln, completing heat exchange and physical and chmical reaction. the clincker cement is discharged to the coller.
Characteristics: 
1) the kiln body is made of high quality killed carbon steel or alloy steel plate and welded
2) The supporting tyre and roller is of ZG*5CrMo and *2CrMo steel
3) The sliding bearing is of non-scraping liner one with large clearance
4) The driving device adopts hard-toothed reducer, flexible sheet coupling, driven by DC motor.
5) Hydraulic thrust roll is used 
6) The kiln head and real seal is of pneumatic or scaled type
7) With slow speed drive 
Kiln specifications: 
Rotary kiln that we made is from diameter 3m x *0mto diameter 6m x *5m.
