· The normal operation of the rotary kiln has a great relationship with the rotary kiln support roller adjustment. During the installation of rotary kiln, firstly make the support roller axis parallel to the center line of the kiln body, at this time if put lead wires into the mesh points between tire and support rollers, the lead wires will be pressed in rectangular strip with same width.
· Rollers inclination. Support roller is a cylindrical components that allow the kiln to work in rotary condition. Properly maintain rollers are clean, free from oil, dust, shiny surface, correctly aligned (where the axis of roller is parallel to kiln axis). Each two rollers carries load (weight) of kiln up to thousand tons.
· The plain bearings in the supporting rollers enable the rotary kiln to run at a low speed with heavy load (12 supporting rollers support 15,000-20,000 kN load) [1-2]. And the operation state of the rotary kiln was largely determined by the working condition of supporting rollers [1-3].
This is done by making slight adjustments to the angle of the kiln support-roller shafts, a process known as "training" the kiln. Training a kiln is tricky and takes practice, or else it can be handled by expert kiln maintenance professionals. Here are some tips to keep in mind! Four Things to Remember When Training Rotary Kiln Support-Rollers

· Own to the rotary kiln such as cement kiln, lime rotary kiln and shaft kiln is widely used in building materials, chemical industry, nonferrous metallurgy industry, black metallurgy, and refractory materials.Rotary kiln''s support roller is an important module, and it has the character of large bearing load, poor working environment, constant running, and complex maintenance.
Kiln Support Roller These support rollers are driven to rotate using friction between roller surface and web. The small friction torque of the roller bearings also allow higher speed operations and helps in avoiding possibilities of slippage due to presence of large air film between roller surface and web.

· Rotary Kiln Vibration. Large, slow moving equipment such as rotary kilns will have a low natural frequency of vibration which in some cases could coincide with a kiln speed. Were this to occur, there would be a pronounced vibration of the kiln on the supporting rollers, and knocking and pounding in the main gear and the gear reducer.
The first rule of operating a rotary kiln without any problem is distributing the forces equally to each piers. This can be done best, by full contact on ring and supporter roller surfaces and minimum ovality in kiln shell. As known; rotary kilns work in %3 – 4 slope depended on design,
· Rotary kiln support rollers: The basic design of rollers has changed little over the years.
