Allan Smith Engineering Private Limited

The thrust roller is an important auxiliary key component of a Rotary kiln. It is designed to limit / control axial movement of a rotary kiln, to ensure uniform wear of tyres and rollers surface on the full width. The thrust roller are divided into two types:

• Mechanical Thrust Roller
• Hydraulic Thrust Roller.

Axial movement is inevitable part of any rotary machine, as the kiln rotate it floats axially on the roller as well. Mechanical thrust rollers usually called as guide rollers and ensure limit on the kiln axial movement, provided on uphill and downhill side. And, hydraulic thrust rollers are provided with axial movement device with usage of the hydraulic system.

Hydraulic thrust roller worn-out due to its constant operation or some abnormal mark created on the surface and reduction in the diameter. The worn out thrust roller is suggested for replacement at earliest, else will damage other components of the rotary kiln.

Preventative replacement of thrust roller is significantly more cost-effective than addressing equipment failure later. The wear is a function of MOC, metallurgy and mechanical parameter like hardness, strength etc. Hardness of the thrust roller plays an essential role in maximizing the equipment life.

As a leading provider of custom rotary equipment, Allan Smith offers high-quality thrust rollers and the replacement at site to required accuracy. We are equipped to monitor the parameters during manufacturing stage to ensure the reliable operation with extended life span.

Due to abnormalities in kiln operating conditions, like:

1.     High shell runout

2.     High tyre wobble

3.     Misalignment in kiln axis

4.     Improper support roller axis, etc

Tyre wobble also called as tyre axial runout or tyre throw and usually consequence of installation error, kiln shell bend thermal or mechanical.

Tyre wobble leads to reduced contact between tyre and   support   roller   in   part   of   kiln   revolution. The reduced contact result in higher hertz pressure on roller  surface  and  has  its  own  consequence  and causes  accelerated  wear  on  rolling  surface  and adversely  affects  kiln  axial  balancing as well. From the above figure, it is obvious the wear is convex on tyre and concave on support roller. The wear begins series of problems like hot bearings, failure of tyre retainers, accelerated wear of raceways etc. Once wear pattern established, accelerated wear can be expected in order to adjust kiln axial movement by adjustment of the worn out support rollers. Due to abnormalities in kiln operating conditions, like:
