Overview of rotary kiln
The shell of the rotary kiln is rolled by
steel plates. The shell is lined with refractory lining and has a
specified slope with the horizontal. It is supported by two or three
wheel belts. A large gear ring is fixed on the inner shell of the span
of the wheel belt attachment at the feeding end with a tangential
spring, and a small gear is engaged with it. During normal operation,
the main drive motor transmits power to the open gear unit through the
main reducer to drive the rotary kiln.
Materials enter the kiln for
calcination from the kiln head (high end of the cylinder). Due to the
inclination of the cylinder and the slow action of the rotary kiln, the
materials roll in the circumferential direction and move in the axial
direction (from the high end to the low end)
The process of
decomposition and calcination is inherited and completed. Finally, the
generated clinker enters the secondary combustion chamber through the
kiln tail cover for calcination again. Exhaust gas generated by
combustion shall be treated. Discharge after passing the test.
