As well known, rotary kiln is an equipment support by supporting roller and drove by transmission gears. There are many factor and fault may leads the phenomenon of apical teeth, for example, the abrasion between riding ring and kiln pads, riding ring and support roller, roller shaft and bearing bus, the kiln shell’s transformation and the support roller’s adjusting, etc. This phenomenon will result in the shake of rotary kiln, costs more motor power consumption, and the bolt become loss. What is more, it may result in the falling off of the rotary kiln.

As a famous large steel casting foundry, Great Wall Steel Casting can handle this problem with years experiences and concluded as follows:

1. Outside move the small gear. Move the small gear up may make the gap bigger. It take advantage of the reservation of bolt hole on reducer seat and motor seat. It is easy and intuitive but with the shortcoming of less adjustment amount.

2. Add pads under the roller seat. Put more pads under the roller seat and engine base allows the kiln central place uplift. This method can only be executed when kiln stop working. And the rotary kiln shall be jacking by jack. Though this work is complicated, but it is free of the limit form roller’s stress state. Therefore, it is better for those who have large adjustment amount.

3. Push the roller inward. This can uplift the kiln centre and make the gap between gears larger than before. It can be executed when rotary kiln is working. But there not too much places for push.
