Trunnion rollers are a critical part of a rotary kiln, responsible for supporting the massive weight of the kiln itself and keeping it rotating smoothly. These rollers are under incredible stress at all times, whether the kiln is in use or not, and must be maintained in good condition for the kiln to run properly.

Even minor problems in the trunnion rollers can ultimately cause a kiln to behave improperly, leading to vibrations, jittery rotation, or even failure of the rotary mechanism. Fortunately, if you have any issues with your trunnion rollers, Kiln Technology Company Company has everything you need to fix them up.

The Most Common Trunnion Roller Problems

Because trunnion rollers are put under so much stress, there are numerous problems they can develop over time.

1. Poor Maintenance

The truth is most trunnion problems are avoidable! Too often we see neglected trunnion rollers that have not received proper lubrication, or where obvious damage was ignored until the kiln was unable to function properly. Contact Kiln Technology Company Company to discuss a maintenance contract that avoids these issues!

2. Over-grinding

It’s common to grind off the top layer of trunnion rollers whenever they get too scratched up, to restore their original smoothly rolling surface. However, over time, this causes the rollers to shrink, changing the speed and rotational profile of your kiln. When this happens, it’s time for new rollers.

3. Excessive skewing

When the roller is tilted to maintain the kiln drum’s position, that is called skewing. However, too much skew will cause the trunnion rollers to wear unevenly. This adds strain, as well as introducing unwanted vibrations to the kiln drum. Over-skewed rollers can typically be repaired, and Kiln Technology Company Company has the expertise!
