Product Introduction Structure Working principle Consist of Daily inspection Technical Parameter

Structure

The cylinder of the rotary kiln is made of rolled steel plates, lined with refractory lining and inclined at a specified angle to the horizontal. It is supported by three pulleys on each support device. A large gear ring is fixed on the inner cylinder near the feeding end pulley with a tangential spring plate, and a small gear wheel meshes with it. During normal operation, the main drive motor transmits power to the open gear device through the main reducer, driving the rotary kiln.

Working principle

The material enters the kiln for calcination from the kiln tail (the high end of the cylinder). Due to the inclination and slow rotation of the cylinder, the material rolls in the circumferential direction and moves in the axial direction (from the high end to the low end), continuing the process of decomposition and firing. After physical and chemical changes, the resulting clinker is cooled by the grate cooler through the kiln hood The fuel is sprayed into the kiln from the kiln head, and the waste gas generated by combustion exchanges heat with the material before being discharged from the kiln tail.
