Structure and Working Principle
Main body of this dry process rotary kiln is rolled by steel plate, with refractory lining inside and shows a certain degree to the horizontal level. Each block support device is supported by three wheel belts. Fix a gear ring in the inner cylinder around feeding wheel belt with cutting spring plate, under it is a meshing pinion. When operating normally, transmit power to open gear device from main drive motor to main reducer to drive this cement clinker rotary kiln.
Material is calcinated in the kiln from its end. Because cylinder tilts and rotates slowly, material both rolls in the circumferential direction and moves in the axial direction (from high to low end). It continues to complete decomposition and calcination through physical and chemical changes. Finally, clinker comes to the cooler for cooling through the kiln head cover.
Fuel is injected into the kiln from kiln head. The exhaust gas will be discharged from the kiln after heat exchanging with material.
