The Abnormal Phenomenon in Operation of Cement Kiln

The abnormal phenomenon in the operation of cement rotary kiln is in the following:

1, any one of the two the axis of the roller in the incorrect location, should be in accordance with relevant roller adjustment measures to adjust.

2, foundation sinking supernormal should reduce kiln speed, study treatment immediately.

3, the power is suddenly cut off, shall immediately start the security power supply with auxiliary transmission timing turn kiln, until the kiln body to cool completely.

4, and shall not directly contact firebrick, forbid to heat up.

5, belt and roller of cement rotary kiln escapes, should immediately report to adjust carefully after find out the reason.

6, roller and belting leather wear into the cause of the polygon and the surface treatment:(1) wheel axis parallel to the center line of the kiln, such as the so-called « big and small figure of eight », etc.(2) transmission gear mesh is not correct,Tooth serious wear and tear caused by impact. (3) the wheel deflection and uneven bearing wear, or bearing appear uneven wear after replace only one bearing.(4) between the roller and belting leather produce sliding and uneven surface wear.(5) the foundation sink, foundation stiffness and vibration enough. (6) roller and belting leather surface wear is too big, poor lubrication bearings produce longitudinal motion. (7) roller and belting leather material uneven or flawed and stiffness unevenness, the surface is ground into a concave or empty edges. (8) the wear is slight, the reason is eliminated automatically after smooth;Must wear more serious when turning to normal use.

7, short-term difficulties starting after stop kiln, usually due to plate kiln kiln camber caused not in time. Usually curved convex part of the next. Such as bending, kiln can be transferred to cylinder bending convex to some upward, pause for a moment, heat bending part of the cylinder.When the temperature is high, must slow turning kiln after a few weeks, then...
