Description

Overview Product Description

Rotary kiln is widely used in processing industries, such as cement, ore processing and chemical. The kiln is a cylindrical shell slightly inclined to the horizontal position and supported by tyres. A Girth gear and pinion assembly rotates the entire system. Material enters the kiln at the upper end and moves to words the lower end. With continuous mixing and a supply of hot air the desired chemical reaction is completed at the lower end and thus the processing is continuous. The kiln shell has a fire brick lining to protect the outer steel shell from the high temperatures existing inside. The tyre is a cylindrical ring supporting to the kiln shell. Tyre is cylindrical cast or forged sin gle ring. Following picture gives general arrangement of tyre and rollers.
Rotary Kiln  Support Roller
Kiln Support Rollers are backed by latest technology and provide desired support to cables and other related products. 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.
Features :
Coming with small friction torque of roller bearings
Rollers are close together that decrease pulling tension
Manufactured as per defined industry standards
Can also be custom designed as per client's specific requirements
Durable finish and reliable performance
We bring forth to our customers Kiln Support Roller for a Rotary Kiln that are designed by our experienced processionals, who hold vast knowledge in this domain. Our professionals uses refractory material that are lined to protect the steel shell and reduce radiation losses.

Installation Instructions


Local over heated places on the shell, drop downs, belts and irregular heat diffusion builds ovality on the kiln shell and this ovality carries the kiln rotation centre out of geometric centre. It is harder to measure and align an eccentric kiln. This situation creates arrhythmic contacts between ring and supporter rollers' surfaces. So the tire and supporter rollers become more stressed and this causes over heating on surface and sides, arrhythmic pressures, yielding, cracks and failures. By the time tire and rollers become concave, convex or conical depending to the situation. The axial pressure creates waves on the surface. A kiln in this position locks itself to up and down movements.
This movement problem over heats the roller shaft beds because of the tire forcing the roller to move up or down and it is harder to align a kiln in this situation because the tire and roller machines each other and all the measurement values changes. All the alignment becomes invalid by the time.
On the other hand; tire and thrust roller contact surface problems causes poor contact and wavy structure on surfaces and irregular movements caused by waves. This situation increases the surface stress and heat-ups the roller beds. Also wrong angles on the surfaces of thrust roller and tire machines the surface and increases the problems.
Harmonic movements create timing marks on the tire surface which behaves like a gear. Geared from starts the small vibrations which will increase and wobble the whole kiln in a very short time.
 
Such a hassled kiln can be tamed only by following where the problem is going and early intervention by grinding (resurfacing) the tire, supporter rollers and thrust roller surfaces. Yet we cannot expect to align such a kiln for a long term use.
For carrying tire and rollers out of the problematic position, the only way is machining and grinding the surface. As a result; contact surface will increase, surface stress and connected problems will end, vibration will end, it will be possible to align the kiln for long term expectations. A hassle-free kiln will collapse down the working costs dramatically.
