Kiln Support Roller Adjustment: Best Methods and Practices

Kiln support rollers play an important role in the overall functioning and productivity of a kiln. They bear the massive weight of the kiln, ensuring its smooth rotation and alignment. However, because of continuous operation and extreme conditions, these rollers are susceptible to wear and tear, requiring routine inspections and adjustments. Understanding the correct methods of kiln support roller adjustment can make all the difference in extending the life of your kiln, so let’s take a look at those.

Risks of Damage to the Support Roller and Expenses

A damaged or misaligned support roller can lead to serious consequences. The repercussions are not only limited to a decrease in production capacity, but can also lead to potential damage to the kiln shell, causing unnecessary wear on other mechanical components, escalating operational costs, and resulting in unexpected downtime.

In the worst-case scenario, a poorly maintained or damaged support roller can even lead to a catastrophic kiln failure, which would require significant resources for repair or replacement. Therefore, the importance of regular maintenance and adjustment of kiln support rollers cannot be understated.

Some Adjustment Methods for Kiln Support Rollers


This involves adding or removing shims under the roller bearings to adjust the height of the roller.


Here, the roller axes are adjusted to be not parallel to the kiln axis, enabling axial movement of the kiln.

Roller migration

In this method, the position of the roller along the kiln axis is changed.

Goals for Adjustment

Keeping the Centreline Straight

The ideal operating condition for a kiln is to maintain a straight centreline. Misalignment can lead to increased stress on the structure and mechanical components of the kiln.

Ensuring the Roller Bears the Kiln Load Evenly

Uneven load distribution can result in excess wear and tear on certain parts of the roller, leading to premature failure.

Allowing the Kiln Cylinder to Handle Normal Reciprocation Crossing the Axis Line

A well-adjusted kiln should be able to manage normal axial oscillations without causing undue stress on the roller or kiln.

Surface Repair for Kiln Support Rollers

Surface repair for kiln support rollers is a critical part of the maintenance process. It involves identifying areas of wear, filling them, and then grinding the roller surface back to its original profile. This process ensures that the roller surface remains smooth and even, allowing for efficient operation and reducing the likelihood of damage to the kiln shell.

The Running-State Repair Device

The Running-State Repair Device is a cutting-edge technology that allows for maintenance and repairs to be performed while the kiln is operational. This device helps to minimize downtime and increases productivity. It uses advanced sensing technology to monitor the roller’s condition and make precise adjustments, ensuring optimal operation and significantly reducing the risk of serious damage.
