Rule of thumb for adjusting rotary kiln rollers

Dec 03, 2015 1. support roller adjustments to control axial thrust (1)Most common reason for adjusting support rollers on a kiln or a dryer (2)It is a best practice to keep light thrust on the downhill thrust roller to minimize over adjustment of the rollers (3)By keeping lighter thrust on the downhill thrust roller the thrust roller will not wear excessively.

The Cost of Improper Tire and Trunnion Adjustment

Feb 27, 2020 Most rotating equipment is designed so that this axial thrust needs to be offset by force developed from skewing the trunnion rollers in a precise manner. The T-Trac® Alignment System establishes a properly skewed trunnion roller setting to thrust the equipment in the uphill direction.

Rotary Drum Training & Float Between Thrust Rollers

When initially training the drum after installation, it may be desirable to favor the most accessible thrust roller to improve ease of training and thrust roller replacement in the future. Make Small Adjustments and Allow Time in Between. Over-adjusting the trunnions is tempting in an effort to make the training process go as quickly as possible.

Since a normal load weighs substantially more than the drum itself, the usual procedure is to so adjust the trunnion rollers, with the drum running under full normal load, as to bring the front tire into light engagement with the rear thrust roller. With such an adjustment properly made, the front tire will lightly engage the front thrust

Photo of the Week: 3D Trunnion Wheel with Thrust Rollers

Today’s photo highlights a trunnion wheel and thrust rollers. The 3D image was produced by FEECO’s in-house design team. Trunnion wheels support the weight of a rotary drum, be it a dryer, cooler, kiln, or granulator. Most importantly, they provide a place for the tire to ride on, acting as a wear piece, since they are more cost-effective to replace than the actual riding ring.
