The ring of rotary kiln will influnce the capacity and waste your fuels ,whatever from profile or save energy,we all should make the ring out.
In general, the ring of rotary kiln is affected by raw material and coal quality, and there are other problems, of course, if once the ring of rotary kiln is formed, the process of stopping kiln in the middle of starting kiln is too complicated. How should we keep the kiln to deal with the ring problem?
First, the heat burning method: through the high temperature to refine the chemical ring, increases the kiln head to enter the coal quantity, reduces the rotational speed of the rotary kiln, reduces the burner air intensity or increases the secondary air volume intensity, reduces the limestone entry quantity, This can be solved at super high temperature for 6 hours. If it can not be solved, please see the second one.
Second, cold burning method: less feed, adjust the secondary air intensity or adjust the air intensity in the burner to make the flame become coarse and short, and calcined until the junction ring disappears without affecting the quality and safety of the rotary kiln. Of course, if it really is not, then continue to look at the third method.
Third, the method of thermal expansion and condensation: to put it bluntly, it is the alternative of cold and hot. By the principle of thermal expansion and condensation, the burner is removed from the ring by adding the calcined high temperature, the material is reduced, and the burner is moved to raise the temperature at the junction, and then through the method of cold burning. Such alternately hot and cold are in principle all can be handled, if this still can not, then only stop kiln maintenance.
These are the more common methods, perhaps you have seen before not seriously understand, please share the Tongjia Industrial several ways to store, because calcined rotary kilns, whether raw materials or coal is not good from the source control, The phenomenon of ring formation should be dealt with in time because it will affect the life of lime kiln and the quality of calcined material will be very poor.
